[libvirt] [PATCH] Fix virCgroupAvailable() w/o HAVE_GETMNTENT_R defined

[Roman Bogorodskiy]

virCgroupAvailable() implementation calls getmntent_r
without checking if HAVE_GETMNTENT_R is defined, so it fails
to build on platforms without getmntent_r support.

Make virCgroupAvailable() just return false without
HAVE_GETMNTENT_R.
