@vmarmol has made the fix upstream for not failing if the capability
being dropped is returned as invalid from the syscall, which is the case
when the capability is not supported on the host.
This is a blocker presently for RHEL6.5 on CAP_SYSLOG. We have patched
around this in our RPM for the time being, but this is the proper fix.

Drop capabilities in dockerinit instead of with lxc utils, since
libvirt-lxc doesn't support it.
This will also be needed for machine container mode, since dockerinit
needs CAP_SYS_ADMIN to setup /dev/console correctly.
