[WPE] MiniBrowser script doesn't proxy Sysprof env vars

https://bugs.webkit.org/show_bug.cgi?id=277363

Reviewed by Nikolas Zimmermann.

The MiniBrowser Python script proxies Sysprof env vars in the
GTK case, but a similar code in WPE is missing.

Move this code to the generic path (GLib) and use it in both
the GTK and WPE.

* Tools/Scripts/webkitpy/port/glib.py:
(GLibPort.setup_sysprof_for_minibrowser):
* Tools/Scripts/webkitpy/port/gtk.py:
(GtkPort.run_minibrowser):
* Tools/Scripts/webkitpy/port/wpe.py:
(WPEPort.run_minibrowser):
