[PATCH v3 1/1] buildtools: avoid break due to failure to cleanup temporary directory

[Andre Muezerie]

When compiling drivers on Windows, instances have been seen where a
temporary directory fails to get cleaned up due to
ERROR_SHARING_VIOLATION (32).

This issue was not seen on operating systems other than Windows.

This patch eliminates the use of tempfile.TemporaryDirectory, which
was triggering the issue.
