[Buildroot] [git commit] package: linuxptp: enhance systemd service

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=85519fc6923c9b670350be2909f73da98ee05307
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

linuxptp now pulls in the time-sync.target, which other services can
use to make sure they have a valid time before starting.

phc2sys (linuxptp-system-clock.service) starts after ptp4l
(linuxptp.service) so we have a valid time before writing it to the
hardware clock.
