libgit2: Enable tests

TestMain() without m.Run() resulted in none of the tests being run.

This libgit2 package contains tests for both managed and unmanaged
transports, enabling it in TestMain() for everything results in the
unmanaged transport tests to not run. Add managed transport
initialization call to all the managed transport tests to allow
unmanaged transport tests to run.
