fnott: remove global properties generation
Rationale:

As of release 1.1.2[1], the configuration ini file supports
declaration of the `[main]` header as an alternative to global
properties by enumerating all sections and mapping each to the
respective parsing function. Global properties will still be parsed
correctly by fnott however generation adds unnecessary complexity to
the module. This commit removes the need for global properties
generation.

Changes:

- Fixed the FIXME at L118.

- Cleaned up unneeded let bindings.

- Changed the generation method to use the `pkgs.formats.ini` from
  pkgs-lib instead of the raw `generators` library. This was done for
  consistency and clarity as the `pkgs.formats.ini` is still required
  for type declaration and uses `generators` internally.

- Removed `global-properties` testcase.

- Updated `example-settings` testcase.

The configuration specified under

written to <filename>$XDG_CONFIG_HOME/fnott/fnott.ini</filename>

generated from the immutable one, useful in scenarios where live reloading is desired.
