We don't like updating to untagged releases, but..

0.2.1 has some regression and upstream is not releasing 0.2.2 or 0.3.0
just yet, so we either need to downgrade to 0.2.0 or go `latest`.

We can hopefully switch back to a tagged release soon.

fix(goofys): fix synapse systemd unit file to correctly require goofys

On Debian 10 (buster) at least, while the Synapse systemd service unit
was referring to Goofys as "matrix-goofys" without a ".service" suffix,
systemd was ignoring the goofys dependency, starting Synapse before
Goofys. All other dependant units which work are using the ".service"
suffix.

This generally leads to the mount path goofys using having been
populated by Synapse before Goofys starts, causing it to fail due to the
mount target not being empty.

The fix seems to be to ensure that the Synapse service unit refers to
Goofys as "matrix-goofys.service".

This change causes the following two lines in
"/etc/systemd/system/matrix-synapse.service":

    Requires=matrix-goofys
    After=matrix-goofys

To be changed to:

    Requires=matrix-goofys.service
    After=matrix-goofys.service

Update jitsi stable-7830 -> stable-7882

dendrite: update config

Update Postmoogle 0.9.4 -> 0.9.5

Fixes a regression introduced in d1b5681ba0.

Looks like `.finished` is a property on the main object, not on some
`.async_result` object.

This also disables self-building on arm64, since it's no longer
necessary: https://github.com/matrix-org/matrix-appservice-slack/pull/656

We were previously trying to reach into `.rc`,
but there's no such thing if `async_result.finished == 0`.
