bitbake: bitbake-selftest: enable specifying tests to run on command line

If you are just trying to fix one test at a time, it can be useful to be
able to specify an individual test(s) rather than running them all:

 bitbake-selftest bb.tests.codeparser bb.tests.cow

You can even specify the test class or function to run, e.g.:

 bitbake-selftest bb.tests.fetch.URITest
 bitbake-selftest bb.tests.fetch.FetcherNetworkTest.test_fetch
