Subject: contrib/paclog-pkglist: rework as bash wrapping awk

Avoid some pain in awk's limited handling of command line arguments by
wrapping this in a Bash script. We also default to
@localstatedir@/log/pacman.log when no args are specified, meaning that
-h or --help is required to get the help message.
