Revert "kheaders: Ignore silly-rename files"

This reverts commit 973b710b88.

As I mentioned in the review [1], I do not believe this was the correct
fix.

Commit 41a0005128 ("kheaders: prevent `find` from seeing perl temp
files") addressed the root cause of the issue. I asked David to test
it but received no response.

Commit 973b710b88 ("kheaders: Ignore silly-rename files") merely
worked around the issue by excluding such files, rather than preventing
their creation.

I have reverted the latter commit, hoping the issue has already been
resolved by the former. If the silly-rename files come back, I will
restore this change (or preferably, investigate the root cause).
