Unprivileged containers can safely mount /sys as read-write. This also allows
systemd-udevd to be started in unprivileged containers.

This reverts commit 2ec47d51.

First, I forgot to actually replace strncpy() with strlcpy(). Second, we don't
want to \0-terminate since this is an abstract unix socket and this is not
required. Instead, let's simply use memcpy() which is more correct and also
silences gcc-8.

gcc-8: silence

The additional \0-byte space added is not needed since IFNAMSIZ needs to
include the \0-byte.

confile: satisfy gcc-8

Apparently -Werror=stringop-overflow will trigger an error here even though
this is completely valid since we now that we're definitely copying a \0-byte.
Work around this gcc-8 quirk by using memcpy(). This shouldn't trigger the
warning.

These files have never been used and as such have no dependencies in the
codebase whatsoever. So remove them. If we need them we can simply pull them
out of the git history.
