tests: Simplify .gitignore

Commit 0bcc8e5b was yet another instance of 'git status' reporting
dirty files after an in-tree build, thanks to the new binary
tests/check-block-qdict.

Instead of piecemeal exemptions of each new binary as they are
added, let's use git's negative globbing feature to exempt ALL
files that have a 'test-' or 'check-' prefix, except for the ones
ending in '.c' or '.sh'.  We still have a couple of generated
files that then need (re-)exclusion, but the overall list is a
LOT shorter, and less prone to needing future edits.
