Bug 1567435 [wpt PR 17932] - Convert frac-linethickness-002 to testharness and extend it, a=testonly

Browse Source 
Automatic update from web-platform-tests
Convert frac-linethickness-002 to testharness and extend it (#17932)

This makes the test a bit more robust by accepting rounding errors.
It also checks a positive length value.
