tests: core: test deinitialization and concurrent initialization Exercise the logic surrounding deinitialization of the libgit2 library as well as repeated concurrent de- and reinitialization. This tries to catch races and makes sure that it is possible to reinitialize libgit2 multiple times. After deinitializing libgit2, we have to make sure to setup options required for testing. Currently, this only includes setting up the configuration search path again. Before, this has been set up once in `tests/main.c`.
