package/kodi: needs .py modules

Kodi segfaults as soon as it tries to load a python module:

    Could not find platform independent libraries <prefix>
    Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
    ImportError: No module named site
    Segmentation fault

Turns out that keeping .py modules (with or without .pyc) fixes the
issue.

Currently, Kodi selects python, but since the format of modules is a
choice, we can not select it.

Fix that by inverting the dependency on python from Kodi:
  - turn it into a depends rather than a select,
  - add the dependency to ! pyc-only
  - update the comment accordingly.

In addition, the !MMU and !static dependencies are updated since they
are no longer needed for Python (we now depend on it rather than
selecting it), but for other packages. The !MMU dependency is moved to
the _ARCH_SUPPORTS symbol as well.

Also, we can no longer "select BR2_PACKAGE_SAMBA4", because samba4
selects python, and we can no longer select python. Therefore, we switch
to a "depends on" dependency for samba4, which is fine as a user willing
to use Kodi with Samba will certainly realize that Samba should be
enabled.

Fixes bug #9221.
