Gating testplans for LLVM

The tests for LLVM are in a separate repo:

• llvm: https://src.fedoraproject.org/tests/llvm.git/

This directory should contain only fmf plans (such as build-gating.fmf) which import the tests from the tests repo. This can be done using the "url" parameter of the plan's "discover" step. Reference: https://tmt.readthedocs.io/en/stable/spec/plans.html#fmf
