bug#38926: pcmanfm-qt unable to open files by double click

[Reza Alizadeh Majd]

Hi, 

there is an issue with `pcmanfm-qt`. when we try to open a known file using
double click, we receive following error:

--8<---------------cut here---------------start------------->8---
Failed to execute child process “gio-launch-desktop” (No such file or directory)
--8<---------------cut here---------------end--------------->8---


since `gio-launch-desktop` is located in `bin` output of `glib` package,
adding that as a propagated input for `pcmanfm-qt` fixes this issue.

is this change is acceptable? if so I can submit a regarding patch to
`guix-patches` mailing list.
