incompatible restrict options for Solaris 10

[Phil-Friderici]

The module is using restrict options that are incompatible with Solaris 10. Because of that the complete line for restrict is ignored leading to an completly unrestricted NTP server.

Error messages show that the restrict lines are ignored (at all)

Feb  5 15:49:21 sol10 xntpd[35808]: [ID 504011 daemon.error] getnetnum: "-4" invalid host number, line ignored

Feb  5 15:49:24 sol10 xntpd[35808]: [ID 373468 daemon.error] adj_frequency: ntp_adjtime failed: Not owner

To restrict ntp on Solaris 10 these line would be sufficient:

restrict default noserve noquery
restrict 127.0.0.1

Should I create a PR with (new) valid defaults for Solaris 10 ?

[Phil-Friderici]

wanna see the PR first ?

[ghoneycutt]

Any PR's in this area are of course certainly welcomed. :)

I don't have testing ability on Solaris 10, so if you are seeing errors, let's get 'em fixed!

@ghoneycutt thanks for merging :)
