[PATCH] Makefile: fix parallel "make test"

[John Keeping]

When building the "test" target we depend on both cgit and building the
Git tools.  By doing this with two targets we end up running make in the
git/ directory twice, concurrently if using parallel make, which causes
us to build more than we need and potentially builds incorrectly if
multi-step build-then-move operations overlap.

Fix this by instead calling back into the makefile so that we alter the
"cgit" target to also build the Git tools.
