bug#48127: [PATCH] gnu: gupnp: Add missing input.

[Jack Hill]

Mathieu,

Thanks for your gupnp fix in 2710df38b0c317bdc69c61c7775d8141eb214dd1. 
Would you mind explaining how you determined gsettings-desktop-schemas 
needed to be a propagated input? I was confused [0][1] about which type of 
input it should be.

Do you think the fix for appstream-glib [2] should also be updated to move 
gsettings-desktop-schemas to propagated-inputs?
