oeqa/buildtools-cases: Allow bitbake time to shutdown

bitbake may still be shutting down when the UI exits. Wait for the lock
to disappear before trying to delete the directory to avoid errors.

Traceback (most recent call last):
  File "/home/pokybuild/yocto-worker/buildtools/build/meta/lib/oeqa/sdk/buildtools-cases/build.py", line 23, in test_libc
    self._run('. %s/oe-init-build-env %s && bitbake virtual/libc' % (corebase, testdir))
