David Owens 3ab5dfb548 libglib2: Avoid absolute path to python in shebang ...

When the output directory is nested under a long path name, calling the
gdbus-codegen, glib-genmarshal, or glib-mkenums scripts throws the
error:

> '/usr/bin/env: /...: No such file or directory'

This is because libglib2 uses the absolute path to the python
interpreter for its shebang statements, and shebangs have a max length
of 127 chars[1]. A long absolute path will be cut off and appear as a
missing file.

Since the host Python is present in the $PATH passed to all packages, we
can copy the workaround from Yocto and just use the python interpreter
in $PATH[2]. However, 'python' is used instead of 'python3' as the
scripts are compatible with both.
