[Buildroot] [PATCH] package/chrony: security bump to version 3.5.1

[Buildroot] [PATCH] package/chrony: security bump to version 3.5.1

[Peter Korsgaard]

Fixes the following security issues:

CVE-2020-14367: Insecure writing of pidfile
-------------------------------------------

When chronyd is configured to save the pidfile in a directory where the
chrony user has write permissions (e.g. /var/run/chrony - the default
since chrony-3.4), an attacker that compromised the chrony user account
could create a symbolic link at the location of the pidfile to make
chronyd starting with root privileges follow the symlink and write its
process ID to a file for which the chrony user doesn't have write
permissions, causing a denial of service, or data loss.

This issue was reported by Matthias Gerstner of SUSE.
