lxc-init: continue even if we fail to mount /dev/mqueue

The 'lxc-init' (a lightweight init process used by lxc-execute in place of upstart etc) tries to mount /dev/mqueue during startup. If that fails (for instance due to missing support for mqueue in kernel) then it aborts execution and returns -1. This is unreasonable as very few applications actually need /dev/mqueue. This similar to what we do with /dev/shm. Signed-off-by: Natanael Copa <ncopa@alpinelinux.org> Signed-off-by: Serge Hallyn <serge.hallyn@ubuntu.com>
