[PATCH 11/20] patman: Clean up creation of the git tree

[Simon Glass]

The test starts with the HEAD pointing to the wrong place, so that the
created files appear to be deleted. Fix this by resetting the tree
before tests start. Add a check that the tree is clean.

Update pygit2 so that the enums are available.
