test: detach the suite handling from the file names

Instead of extracting the suite name from the test's file name use the
current suite that is being parsed. This way we pave the way for
multiple suites in the same file.

This uses a global because otherwise we'd have to redo all the
litest_add() functions but it does the job here.
