[PATCH] Better cleanup in TLS tests for -13beta2

Hi,

This patch removes two temporary files that are not removed. In
Debian, repeated builds fail. We do not allow builds from modified
sources.

The first file was clearly an oversight. It was created separately. I
am not sure why the loop over @keys did not remove the second.

For the record, the error message from Debian is below. Lines 25-27
show the files that were left behind.

Kind regards,
Felix Lechner
