redhat: mockbuild updates for repoquery
for starters, mock should be careful not to use parent yum cache
when running repoquery, the host runs it, we want the guests's
yum cache. be careful to not attempt to use the parent's yum cache
(in the default config).
additionally, we need to not try to build 64 bit kernel modules in
32 bit chroots. expand the list of rpms while ejecting any which are
64 bit if we're 32.
additionally, blacklist kernels which are the wrong osver.
