gnu: trytond: Ensure all modules are found.
If the python package matching trytond is not installed alongside to trytond, PYTHONPATH is not set (or pointing to a wrong version) and trytond (and the trytond tools) would not find the trytond modules. This change introduces a new native-search-path GUIX_TRYTOND_MODULES_PATH. Trytond gets patched to honor this environment variable. Thanks to Maxim Cournoyer, whose code for guix-pythonpath-search-path was the template for guix-trytonpath-search-path. * gnu/packages/patches/trytond-add-guix_trytond_path.patch: New file. * gnu/local.mk: (dist_patch_DATA): Add it. * gnu/packages/tryton.scm (trytond): Use it. [native-search-paths]: New element. (guix-trytonpath-search-path): New function.
