[PATCH v2] t/.gitattributes: only ignore whitespace errors in test files

Only ignore whitespace errors in t/tNNNN-*.sh and the t/tNNNN
subdirectories (since they can contain test-relevant trailing
whitespace).  Other files (like test libraries) should still be
checked.

Also fix a whitespace error in t/test-lib.sh.

What is the difference between test-lib.sh and tNNNN-*.sh that makes one
subject to whitespace checking and the other not?

I thought that was obvious since they had been not been checked before
either (see the diff). :) Anyways, added explanation in parens in the
commit message; nothing else has changed since v1.
