github: Fix testing openmp in the runtimes build

This makes sure the openmp tests actually are executed; since
switching to the runtimes build of openmp for the tests (in
98684ab807), the tests weren't
executed, as it no longer found the tools necessary for executing
the tests - as they are expected to be specified differently
in the runtimes build mode.

This requires the commit 48a5119d8e7d7236a28c14d06ec215ef3366ef90
(backported to 22.x in 9794a7932465bdc244b327388905d66df38485e2,
part of the 22.1.1 release) in llvm-project, to be able to run
tests without actually building clang in the same build as the
test tools.
