Subject: [PATCH] scripts: add check_program, to run tests easily

* scripts/check_program: New script, so you can easily run all tests
relating to a certain program. Takes less time than checking all
programs with 'make check', and quicker to type than
'make check TESTS=TEST1,TEST2,TEST3' for multiple tests.
