Compliment the existing GIT_TEST_INSTALLED variable added in [1] with
one that allows for testing a git built in a directory that's not
"../".

Instead of "test this installed git" ("GIT_TEST_INSTALLED"), this new
"GIT_TEST_BUILD_DIR" is a "test this built directory over
there". E.g. this will pass all tests:

	git clone --depth=1 https://github.com/git/git.git git1
	cp -R git1 git2
	make -C git1
	[apply this change to git2]
	(cd git2 && GIT_TEST_BUILD_DIR="$PWD/../git1" make -C t prove)

This facility and file-based instructions to have the test suite use
another build directory[2] are mutually exclusive, but in a subsequent
commit we'll make CMake use this instead.

1. 6720721e152 (test-lib.sh: Allow running the test suite against
   installed git, 2009-03-16)
2. 350a005e366 (cmake: avoid editing t/test-lib.sh, 2022-10-18)
