Fix fedora-minimal on CentOS builds

Browse Source 
As described in the comments, CentOS overrides the "distroverpkg"
variable in yum.conf.  This is the package that yum queries to
establish the value of the $releasever variable.  On other platforms,
this defaults to "redhat-release" (which "fedora-release" provides) so
everything works.  It is only when the base-system "distroverpkg"
refers to a package not in the chroot we hit the issue.

We can avoid this by setting the releasever variable via the
commandline.
