purge-distfiles: grep instead of sourcing template

Browse source 
To catch all SHA256 hashes from a template, even the ones which
are used only under certain preconditions, use grep [0-9a-f]{64} to
find all hashes in a template.

The may be some false positives which does not hurt the intended
purpose to purge obsolete distfiles.
