Firefox packaging changed upstream, renaming the desktop files. This
caused the mime applications to be stale, so update those.

eog is a nice image viewer that works pretty well on a
touchscreen/mobile display.
Nemo is a file manager from the Cinnamon desktop project, which forked
from Nautilus some time ago. It is much more usable than Nautilus on a
touchscreen/mobile display.
Set eog as default app in mimeapps.list, so it even works when hiding
the launcher with postmarketos-hidden-desktop-entries (we'll hide it,
because it doesn't work when opened directly; no image is shown and
opening a file does not work either). The list of associated mimetypes
is taken from here:
https://gitlab.gnome.org/GNOME/eog/-/blob/master/data/org.gnome.eog.desktop.in.in
Add mimeapps.list, so links clicked in postmarketos-welcome and other
applications properly open in firefox. Without this patch, they just
don't open at all.
Bump the pkgver instead of the pkgrel, so the APKBUILD is in sync again
on both master and v20.05 (right now, the pkgrel on v20.05 is ahead by
one, otherwise the file is the same).
