Firefox 81 introduced a new print dialog. Under NixOS, this dialog
offers only "Save as PDF" as the destination. To print to a real
printer, one has to click "Print using the system dialog" and print
from there. This is not only one unnecessary extra click, but the
system dialog also does not offer preview.
With this commit, Firefox starts offering real printers in its
printing dialog, removing the above mentioned deficiencies.
CUPS is needed because Firefox uses dlopen() to load libcups.so.2 at
runtime. See

In order to make the man pages accessible, the previous code used
nix-support/propagated-user-env-packages. However this file is also used to set
the PATH when the application is executed with `nix run`, thus including the
wrapped and the wrappee in the environment.
Having the wrappee enumerated first in the environment caused `firefox` to
default to the wrappee, and as such not being able to find a proper GTK. This
was a source of failures while opening a file-picker.
This change removes the code to propagate the wrappe in the environment, as the
man pages are already linked in the wrapper output.
