test: refactor all tests that depends on crypto

we had a few ways versions of looking for support before executing a test. this
commit unifies them as well as add the check for all tests that previously
lacked them. found by running `./configure --without-ssl && make test`. also,
produce tap skip output if the test is skipped.
