[PATCH] test-lib: simplify GIT_SKIP_TESTS loop

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.

I am probably making a complete shell fool out of myself by overlooking
something completely trivial.

But just in case I am not, this reduces the loop from O(N^2) to O(N), although
I do admit that N is typically not that large...
(Note that the inner $skp does not overwrite the outer one, at least not with bash.)
