[arch-projects] [dbscripts] [PATCH 2/3] ftpdir-cleanup, sourceballs: replace external find command with bash globbing

This fully removes the use of find from the codebase, leads to a
micro-optimization in a couple cases, and ensures that $PKGEXT is
consistently treated as a shell globbing character (which is important
because it is used as one).
Of the eight instances in these files:
- One was unnecessary as `cat` can natively consume all files passed to
it and no directory traversal was in use.
- Two were unnecessary as they were hardcoded to read a single file....
- Another four were only being used to strip leading directory paths,
and can be replaced by globstar and ${filepath##*/}
- The final two were checking the modification time of the files, and
can be replaced with touch(1) and [[ -nt ]]. Although this introduces
an additional temporary file, this is not such a big deal.
