cooker.py: Ensure only one copy of bitbake executes at once
The bitbake codebase makes assumptions that only one copy is active
against a given build directory at a given time. This patch adds a
lockfile in TOPDIR to ensure that is the case.
Note that no unlock is needed, that is automatically dropped when
execution terminates.
