gstreamer: Add meson devenv support
This change to the build system will prepend the plugin build directory
to GST_PLUGIN_PATH environment. This makes the built plugin visible to
GStreamer inside meson devenv enabling uninstalled testing. In order to
avoid polluting the user registry, the GST_REGISTRY environment is also
set.
