[PATCH] test-lint-duplicates: Only check for numbered test cases

["Torsten Bögershausen" <tboegi@web.de>]

Running make inside contrib/remote-helpers fails in "test-lint-duplicates"

This was because the regexp checking for duplicate numbers strips everything
after the first "-" in the filename, including the prefix.

As a result, 2 pathnames like
"xxxx/contrib/remote-helpers/test-bzr.sh" and
"xxxx/contrib/remote-helpers/test-hg-bidi.sh"

are both converted into
"xxxx/contrib/remote", and reported as duplicate.

Improve the regexp:
Remove everything after tNNNN- (where X stand for a digit)
