foot: 1.8.2 -> 1.9.0

https://codeberg.org/dnkl/foot/releases/tag/1.9.0

Main change requiring intervention from our side is the new alternative
terminfo install location used by foot in order to coexist with ncurses'
install location.

We want to keep using the normal terminfo install location:

* ncurses and foot have separate store paths so there won't be an
  actual conflict

* buildEnv etc. can deal with file conflicts when building the
  system path

Since foot now sets the TERMINFO environment variable to its terminfo
directory, we can stop installing foot's terminfo globally always (via
propagated-user-env-package) instead `foot.terminfo` now only needs to
be installed on remote systems were you want to have the proper terminfo
for foot.

We'll need to see if this works reliably in the future. NixOS sets
TERMINFO_DIRS, so there may be packages that have been patched to
respect that, but not TERMINFO.
