File remove-chown-chmod.service.patch of Package quagga

References: bsc#1191890,CVE-2021-44038
Upstream: no

The services ensure using ConditionPathExists that configuration
files exist at start time.

This change reverts to quagga-1.1.1 service behavior and removes
the attempts to fix configuration file ownership and permissions
that may lead to local privilege escalation from quagga to root.
