  [lldb/test] Tolerate ENOENT when cleaning per-test build directory (#203072)

makeBuildDir() removes any leftover bdir from a prior run before the new
test starts. shutil.rmtree() walks the tree via scandir+unlink, so if an
entry vanishes between those two calls it raises FileNotFoundError and
the test aborts in setUp.

We see this on bots when a previous test's implicit clang module build
left a *.pcm.lock file behind. clang's LockFileManager ties the lock's
lifetime to the holding process, so the file can disappear under us as
soon as that process exits.

Pass an onerror handler that swallows ENOENT (the entry is already gone,
which is what we wanted) and re-raises anything else.
