gstreamer: correctly set GST_PLUGIN_SCANNER_1_0

The order was wrong: GST_PLUGIN_SCANNER_1_0 was previously set before
GTKDOC_EXTRA_ENVIRONMENT and so was overriden by upstream setting it
from there. This changes the location of GST_PLUGIN_SCANNER_1_0 setting
to come after GTKDOC_EXTRA_ENVIRONMENT.

+
 Patch the gtk-doc makefiles so that the qemu wrapper is used to run transient
 binaries instead of libtool wrapper or running them directly.
