fix: $HOME/bin PATH, vertical monitor resolution, update ghc

configuration.nix:
- FIX `$HOME/bin` PATH: `$HOME/bin` wasn't part of PATH anymore, xmonad need
it for `dmenu_run`, .xsession doesn't help. Added
`xserver.displayManager.sessionCommands` script that executes before
wm and fixes path.
- FIX mouse accel: deactivated mouse accel with xset in
`sesssionCommands` too.

desktop.nix:
- FIX vertical monitor: xserver has a default `resolutions` field.

xmonad:
- little cleanup I did while trying to fix `$HOME/bin` path

.shell/env:
- more consistent path

system packages:
- update ghc to ghc882
- removed p7zip because deprecated
- commented nomacs out because it couldn't build
