Since for some reason upstream grep deprecated "fgrep", and for some reason
fedora packagers followed suit, some these tests scripts fail with the goofy
"fgrep: warning: fgrep is obsolescent; using grep -F" warning.
Find new home for downstream RHEL tests. Upstream them. The set of
tests used for fedora gating stays intact: The gating tests are only
those having the tier1 tag set in their main.fmf file. The testplan
plans/ci.fmf filters the others out from gating.
The set of Fedora gating tests stays the same as it was before this
change.
