Update package list

Arch system packages are recategorized and alphabetized, the script
portion of the file is updated to make it simpler to port to other
platforms of interest, and the file is renamed to something more
generic.

The end result of all this package shuffling is the following:

package         action          explanation

alsa-plugins    removed         Noreq*, Little used by me
mesa            removed         Noreq*, OOS** for base system
vi              removed         No longer required for visudo
xcb-util        removed         Noreq*
xorg-xrandr     now implicit    Implied by lxrandr
gnu-netcat      replaced        with netcat (should result in same pkg)
file            added           Prev given by base, now explicit
p7zip           added           Add common archive tools

  **   OOS = Out of scope
