glib-genmarshal: Avoid a string copy for static string valist arguments

Browse Source 
When building a valist marshaller, we can avoid a string copy if the
argument is known to always be static. The marshaller we ship in
`gmarshal.c` got this right, but marshallers generated by
glib-genmarshal were missing the optimisation. Fix that.

Backported version of !904 does not include the unit test. The version
of this on `master` includes a unit test.
