[tools] testbot/TestWTBS: Fix matching regexps in patches.

[Francois Gouget]

That step was getting skipped for patches submitted through the
mailing list, i.e. whenever CheckJobTree() was first called from
CheckPatch() (which checks the patches/* files) rather than straight
from CheckJobs().

Sending the 100+ wtbsuite test cases is normally done through
WinePatches*Submit.pl, that is as if coming from the mailing list,
resulting in that check being skipped.
Found thanks to the testwtbsuite test suite.
