Subject: Generate test git-repos instead of committed binaries

Instead of having test repos: foo, bar and init committed in a
binary form, generate them using the test/gen* scripts before
starting the first 'test' session. Running 'make clean' removes
the generated test repos.
The original 'binary' test repos are being handled via d/rules
while still existing upstrem.
