Makefile: build libgit-rs and libgit-sys serially

"make -JN" with INCLUDE_LIBGIT_RS enabled causes cargo lock warnings and can trigger ld errors during the build. The build errors are caused by two inner "make" invocations getting triggered concurrently: once inside of libgit-sys and another inside of libgit-rs. Make libgit-rs depend on libgit-sys so that "make" prevents them from running concurrently. Apply the same logic to the test invocations. Use cargo's "--manifest-path" option instead of "cd" in the recipes.
