Merge `doc/unit-tests.md` into `src/test/README.md`

Refer to the right file in the top-level README.md.

Having only one file with test documentation saves some confusion about
where things are documented.

 ### bitcoin-util-test.py
 
 The test directory also contains the bitcoin-util-test.py tool, which tests bitcoin utils (currently just bitcoin-tx). This test gets run automatically during the `make check` build process. It is also possible to run the test manually from the src directory:
