boost: 1.79 -> 1.81

[tobim]

Description of changes

Updates boost to the most recent version minus one. The idea is to stay behind one release in the hope that most of the breakage caused by that version has been resolved in the upstreams in the meantime.

This also removes the boost17x and boost18x aliases. They suggested that the inner numbers 7 and 8 represent some kind of minor version, which is not the case.

@wegank may I ask you for a review?

[wegank]

I guess I don't have the computing power for the review, but I'll try to get the commit dropping boost17x and boost18x merged first.

I guess I don't have the computing power for the review

Isn't that one of the reasons staging exists?

This is probably what broke all compiled libreoffice variants: https://hydra.nixos.org/build/228218374/nixlog/1/tail

We can probably just use boost 1.79 for libre office
