dev-pkgs: do not install gstreamer -dev packages
dev-pkgs: do not install gstreamer -dev packages

ostro-xt-image uses dev-pkgs image feature to install *-dev
complementary packages in the image.

However, with gstreamer -dev packages we want to make an
exception. The exceptions can be listed as regular expressions
in PACKAGE_EXCLUDE_COMPLEMENTARY. The full dependency chain,
including the packagegroup-multimedia-dev, must be listed.
