glib: Use a correct python in scripts when cross-compiling.

Browse source 
During the build, a native python should be used as these
scripts will be invoked during the build, but when installed,
they should be a python for the system we're compiling for.

* gnu/packages/glib.scm
  (glib)[arguments]<#:phases>{patch-python-references}: Look up
  "python" in 'native-inputs', not 'inputs'.
  (glib)[inputs]{python,python-wrapper,bash-minimal}: New inputs.
