eSDK.py: avoid error in tearDownClass due to race condistion

When removing the temporary directory, it's possible that bitbake.lock
file is removed by bitbake during the cleanup. And this leads to the
following error.

  FileNotFoundError: [Errno 2] No such file or directory: 'bitbake.lock'

So add a check to remove this file before cleaning up the temporary
directory.
