[debuginfo-tests] Use built lldb for testing if available (#131681)
The cross-project-tests's debuginfo-tests don't rely on lldb being built
to run. While this is a good, a bug in the system lldb can cause a test
to fail with no way of fixing it. This patch makes it so the tests use
the built lldb instead if it's available.
