briar-gtk flatpak on librm5_devkit
here the (admitteldy hacky) steps to reproduce
getting briar-gtk alpha flatpak to work on librm5_devkit aarch64
## patched briar headless
cloned briar repo
applied two patches:

compiled briar-headless

## briar-gtk build flatpak
git cloned:
https://code.briarproject.org/briar/briar-gtk
`git submodule update --init`
built flatpak as advertised via:
`flatpak-builder --install-deps-from=flathub --user --install --force-clean --ccache flatpak-builddir app.briar.gtk.json`
## run shell in flatpak container
`flatpak run --command=sh app.briar.gtk`
first replacing briar headless with the patched version for aarch64
`cp /home/purism/dl/briar/briar-headless/build/libs/briar-headless.jar /home/purism/.local/share/flatpak/app/app.briar.gtk/aarch64/master/active/files/briar/briar-headless.jar`
starting briar headless inside the flatpak
`java -jar /app/briar/briar-headless.jar`
which complains about the not visible (from flatpak perspective) distro tor dependencies.
so copy dependencies into flatpak as well:
libevent-2.1.so.6:
`cp /usr/lib/aarch64-linux-gnu/libevent-2.1.so.6.0.2 /home/purism/.local/share/flatpak/runtime/org.gnome.Platform/aarch64/3.36/active/files/lib/aarch64-linux-gnu/libevent-2.1.so.6`
libzstd.so.1:
`cp /usr/lib/aarch64-linux-gnu/libzstd.so.1.3.8 /home/purism/.local/share/flatpak/runtime/org.gnome.Platform/aarch64/3.36/active/files/lib/aarch64-linux-gnu/libzstd.so.1`
with that briar-headless runs fine.
## briar-gtk python key error
python key error, so I disabled the two lines of code:
remove/comment-out lines 30 and 31 of
/home/purism/.local/share/flatpak/app/app.briar.gtk/aarch64/master/active/files/lib/python3.7/site-packages/briar_wrapper/models/contacts.py
