Log message:
hs-*: add PLIST files

These PLIST files have been autogenerated by mk/haskell.mk using
HS_UPDATE_PLIST=yes during a bulk build.  They will help to track changes
to the packages.  The Haskell packages didn't have PLIST files because
their paths contained package hashes.  These hashes are now determined by
mk/haskell.mk, which makes it easy to generate easy to read PLIST files.

Log message:
Import hslua-module-system-0.2.1

Provides access to system information and functionality to Lua scripts
via Haskell's System module.

Intended usage for this package is to preload it by adding the loader
function to package.preload. Note that the Lua package library must
have already been loaded before the loader can be added.
