games: Replace RMD160 checksums with BLAKE2s checksums

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

Log message:
mk: make BROKEN a list of lines, like PKG_FAIL_REASON

Packages defined the variable BROKEN inconsistently. Some added quotes,
like they are required in PKG_FAIL_REASON, some omitted them.

Now all packages behave the same, and pkglint will flag future mistakes.

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.
