[PATCH] test-lint-duplicates: consider only numbered test cases

Running make inside contrib/remote-helpers may fail 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-XX.sh" and
"xxxx/contrib/remote-helpers/test-YY.sh"

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

Improve the regexp:
- strip the leading path and look only at the basename
- only look at files which have tNNNN- (where N stand for a digit) in the name
