Subject: [PATCH] gnu: python-pyinotify: Reduce package closure size.

This Python package can be used both as a library and as a standalone
command line application.  It does so by adding a shebang to the library
code. Dropping this shebang prevents the build system from adding
python-wrapper as an input, reducing package closure size from
~200 MiB to ~0.2 MiB.  A new python-pyinotify-cli package is added to
allow users who desire so to use the CLI application.

* gnu/packages/python-xyz.scm (python-pyinotify)[phases]{drop-shebang}:
New phase.
(python-pyinotify-cli): New variable.
