buildah-bud tests: add arg sanity check

Fix bad design decision (mine) by adding a simple usage check to 'skip'
and 'skip_if_remote' functions: if invoked without test-name args,
fail loudly and immediately.

Background: yeah, their usage is not intuitive. Making the first arg
be a comment helps with _reading_ the code, but not _writing_ new
additions. A developer in a hurry could write "skip this-test" and,
until now, that would be a silent NOP.

Tested by adding broken skip/skip_if_remote calls inline; I confirm
that the line number and funcname usage is correct.
