t/README: mention test files are make targets
Since 23fc63bf8f (make tests ignorable with "make -i", 2005-11-08), each test file defines a target in the test Makefile, such that one can invoke: make *checkout* to run all tests with 'checkout' in their filename. This is useful to run a subset of tests when you have a good idea of what part of the code is touched by the changes your are testing. Document that in t/README to help new (or more seasoned) contributors that might not be aware.

Since the tests all output TAP (see https://testanything.org) they can

be run with any TAP harness. Here's an example of parallel testing
