contrib/pacdiff : rework and cleanup

I initially only wanted to add a -l/--locate option to use locate instead of
find, which should have been easy.

Then I thought I would try to support filename with whitespace while I was
at it, and this was a bit more complex. The safest ways seem to be the
following ones : http://mywiki.wooledge.org/BashFAQ/020

Then I received a lot of suggestions on #bash about how to improve the
script, which I tried to address.
