[gpgme][PATCH] build: lang: python: cleanups

1. Make setup.py executable when generated.

2. Add prepare target to enable prepare the source tree without building
   anything. This is handy to enable standard distutils build outside of
   gpgme build system.

3. Treat data.h in similar manner as other VPATH issues, just symlink it
   to the srcdir to simplify build, remove the CFLAGS requirement of
   distutils.

The above does not alter the behavior of current build but supports the
following sequence:

$ mkdir build
$ cd build
$ ../configure --enable-languages=
$ make
$ cd lang/python
$ make prepare
$ ./setup.py build
$ ./setup.py install

Notice the standard use of distutils which is required for package
manager to control the python selection and build process.
