Caps are getting lost when cloning an LXC. Adding the -X parameter copies the extended attributes. This allows things like ping to continue to be used by a non-privilged user in Debian at least.

When setting lxc.network.veth.pair to get a fixed interface
name the recreation of it after a reboot caused an EEXIST.
-) The reboot flag is now a three-state value. It's set to
1 to request a reboot, and 2 during a reboot until after
lxc_spawn where it is reset to 0.
-) If the reboot is set (!= 0) within instantiate_veth and
a fixed name is used, the interface is now deleted before
being recreated.

zypper info's output is not usable for several reasons:
* it is localized -- there is no "Version: " in my output
* it shows results both from the repo and local system

So use plain rpm to determine whether build is installed and if proper

1) Two checks on amd64 for whether compat_ctx has already
been generated were redundant, as compat_ctx is generally
generated before entering the parsing loop.

2) With introduction of reject_force_umount the check for
whether the syscall has the same id on both native and
compat archs results in false behavior as this is an
internal keyword and thus produces a -1 on
seccomp_syscall_resolve_name_arch().
The result was that it was added to the native architecture
twice and never to the 32 bit architecture, causing it to
have no effect on 32 bit containers on 64 bit hosts.

3) I do not see a reason to care about whether the syscalls
have the same number on the two architectures. On the one
hand this check was there to avoid adding it to two archs
(and effectively leaving one arch unprotected), while on
the other hand it seemed to be okay to add it to the
same arch *twice*.

The entire architecture checking branches are now reduced to
three simple cases: 'native', 'non-native' and 'all'. With
'all' adding to both architectures regardless of the syscall
ID.

Also note that libseccomp had a bug in its architecture
checking, so architecture related filters weren't working as
expected before version 2.2.2, which may have contributed to
the confusion in the original architecture-related code.

systemd services like logind and journald need CAP_SETFCAP CAP_SETPCAP

Updated centos/fedora/oracle templates to use `hostname` for DHCP_HOSTNAME in
/etc/sysconfig/network/ifcfg-eth0, so the container's host name is propagated
to the host's DHCP server (e.g. dnsmasq, which also acts as the DNS server).

Documents setpcap,sys_admin,sys_resources as breaking systemd, but does not drop them from lxc.cap.drop, as the default init system on Gentoo is OpenRC, thus stuff breaking systemd can be blocked anyway.

This also drops setpcap and sys_nice caps, as these are also dropped in other non-systemd distros.

Most of the explanatory blurb was copied from other distros' configs.
