[Libguestfs] [PATCH] inspection: fix CentOS 7 detection
In newer CentOS 7 versions /etc/redhat-release says that the distro is
derived from RHEL, so we need to look at /etc/centos-release for
actually identifying it as CentOS.
The old code is needed as sub-case of /etc/redhat-release, as on
CentOS < 7 that file is a symlink to /etc/centos-release.
