The pcfile argument passed to get_target_install_filename() is
guaranteed to be a Path() object so use the .open() method to open the
file instead of the standard open() function.
This makes it possible to run gst-env.py on older systems with pyhton3.5
where the standard open() function cannot handle Path arguments.
The change fixes errors like the following:
