[OE-core] [PATCH 1/1] eSDK.py: avoid error in tearDownClass due to race condistion

[Chen Qi]

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.
