openSUSE: 2022:0016-1 Important: Watchman Local Escalation Fix

This update for watchman fixes the following issues:

- ship README.suse that explains how to use the template systemd units

- add user writable bit for systemd service and socket files

- properly handle state directory creation in /run/watchman/$USER-state.

The former approach was susceptible to a local privilege escalation

using symlinks (CVE-2022-21944, boo#1194470).

- Added hardening to systemd service(s) (boo#1181400). Modified:

* watchman@.service

- removed python2 bindings

- enabled python3 bindings as python3-watchman

- Changes in 4.8.0:

* New command `flush-subscriptions` to synchronize subscriptions

associated with the current session.

* Enforce socket Unix groups more strongly ??? Watchman will now

refuse to start if it couldn't gain the right group memberships, as

can happen for sites that are experiencing intermittent LDAP

connectivity problems.

* pywatchman now officially...
