[bug#68937] [PATCH 1/3] gnu: orca: Fix invocation errors.

[Dariqq <dariqq@posteo.net>]

at-spi2-atk causes 'import pyatspi' to fail.
Add orca libraries to GUIX_PYTHONPATH such that the orca modules can be found.

* gnu/pacakges/gnome.scm (orca)[inputs]: Remove at-spi2-atk.
[phases] wrap-orca: Add self to GUIX_PYTHONPATH.
