[libvirt] [PATCH] build: fix recent syntax-check breakage

[Eric Blake]

The use of readlink() in lxc_container.c is intentional; we don't
want an absolute pathname there.

* src/util/cgroup.h (VIR_CGROUP_SYSFS_MOUNT): Indent properly.
* cfg.mk (exclude_file_name_regexp--sc_prohibit_readlink): Add
exemption.

Pushing under the build-breaker rule.
