[PATCHv2] test-lib: simplify GIT_SKIP_TESTS loop

[Michael J Gruber <git@drmicha.warpmail.net>]

04ece59 (GIT_SKIP_TESTS: allow users to omit tests that are known to break, 2006-12-28)
introduced GIT_SKIP_TESTS, and since then we have had two nested loops
iterating over GIT_SKIP_TESTS with the same loop variable.

Reduce this to one loop.

v2 is simplified even more and is really Junio's patch.
