tests: introduce make targets check-expensive and check-very-expensive

* Makefile.am: add shortcuts to run (very) expensive tests.
Use "make check-expensive" to run tests with RUN_EXPENSIVE_TESTS=yes,
use "make check-very-expensive" to run tests with both
RUN_EXPENSIVE_TESTS=yes and RUN_VERY_EXPENSIVE_TESTS=yes.
Non-expensive tests are included in all cases.
