meson: remove deprecated ExternalProgram.path

Replaced by full_path:
https://mesonbuild.com/Reference-manual_returned_external_program.html#external_programpath

ExternalProgram.full_path was added in meson 0.55 but we support meson
>= 0.51. Because of that, use path or full_path conditionally depending
on the meson version.

This gets rid of the following deprecation warning:
  NOTICE: Future-deprecated features used:
   * 0.48.0: {'module python3'}
   * 0.55.0: {'ExternalProgram.path'}
