Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
nautilus could not be built reproducibly.

This is because the org.gnome.Nautilus.metainfo.xml file contains the
current build date:

│ │ │ │ │    <project_license>GPL-3.0-or-later</project_license>

A patch is attached that seeds this date from SOURCE_DATE_EPOCH if it
is available in the environment.
