[Buildroot] [git commit branch/next] ptpd: systemd support

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=9ad7b47c5ee1a69dc3540f1da75dce8b07f2c234
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

[Thomas:
   - use relative symbolic link instead of absolute one
   - remove the -S option, since redirecting stdout is not needed,
     it's already taken care of by systemd. Suggested by Maxime
     Hadjinlian.]
