upgrade to 0.2.0 and solve permissions issue
* Update checksum and upstream URL (#11)

Upstream URL changed, this is mentioned in this week's edition of TWIM:
https://matrix.org/blog/2021/08/06/this-week-in-matrix-2021-08-06#mautrix-

* Fix upgrade script (#14)

The destination directory for upgrade source was wrong, so upgrading would reinstall the previous version.

* add default-jre-headless

* upgrade pip

* Update config.yaml

* Add mautrix_signal to the signald group, set permissions

Unfortunately signald creates folders with the wrong permissions, so
there is still an issue with sticker subfolders.
