When running "make test" with TEST_CONTRIB_TOO=yes (which is default in
macOS CI workflows), $(MAKE) -C contrib/ test is invoked. However,
contrib/Makefile only invoked tests for diff-highlight and subtree,
meaning git-credential-osxkeychain was never built or verified during
standard CI test runs.
Add a "test" target to contrib/credential/osxkeychain/Makefile that
depends on building git-credential-osxkeychain. Additionally, wire up
credential/osxkeychain in contrib/Makefile under "all", "test", and
"clean" whenever running on macOS (Darwin).
This ensures that running "make test" or "make all" in contrib on macOS
automatically builds and links git-credential-osxkeychain, preventing
future build or symbol linking regressions from slipping through CI.

Recently it was reported that a topic merged to 'next' broke build
and test for contrib/subtree part of the system.
Instead of having those who run 'next' or 'master' to hit the build
and test breakage and report to us, make sure we notice breakages in
contrib/ area before they hit my tree at all, during their own
presubmit testing.
