[cache_repair, thin_repair] fix bug introduced in recent patch

Browse Source 
I hadn't realised that check_file_exists() also checked that it was
a regular file, which we don't want for the couple of uses I recently
added.

This patch adds an optional arg must_be_regular_file, and defaults
it to true, preserving the original behaviour.  The recent additions
have this set to false.
