games: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

games: Remove SHA1 hashes for distfiles

Log message:
games/*: fix alignment of variable values

pkglint -Wall -r --autofix --only aligned

After running the above command, three packages had to be adjusted
manually:

In maelstrom-x11, pkglint didn't see that a commented variable
assignment should have been re-aligned as well.

In netmaze, there was a single line that didn't align well with all the
others, but pkglint decided to adjust the whole paragraph to this single
line. The result would have been ok, but not good.

In tscp, there was a paragraph where some of the lines were indented
one space more than the others. This rule is useful when one variable
name is very long compared to the others, but not in this case.

Import ioquake3-raspberrypi-20150118 as games/ioquake3-raspberrypi.

ioquake3 is a game engine project which aims to build upon id Software's Quake
3 source code release. The source code was released on August 20, 2005 under
the GPL.

The project's goal is to create a bug-free, enhanced open source Quake 3
source code distribution upon which new games and projects can be based, as
well as an improved version (in relation to the original binaries) of the
engine for playing Quake III: Arena, the Team Arena expansion pack and all the
popular mods.

This version of the package is optimized for the Raspberry Pi.
