configure.ac: fix build without stack-protector

Compiler based hardening (including -fstack-protector-strong) are
enabled since version 3.0.3 and
https://github.com/lxc/lxc/commit/2268c27754152aa538db2c9e3753d72d19bcd17a

However, some compilers could missed the needed library (-lssp or
-lssp_nonshared) at linking step so use ax_check_link_flag instead of
ax_check_compile_flag

apparmor: allow various remount,bind options

RW bind mounts need to be restricted for some paths in
order to avoid MAC restriction bypasses, but read-only bind
mounts shouldn't have that problem.

Additionally, combinations of 'nosuid', 'nodev' and
'noexec' flags shouldn't be a problem either and are
required with newer systemd versions, so let's allow those
as long as they're combined with 'ro,remount,bind'.
