net-misc/ntp: add 4.2.8_p16

We don't need to generate our own man pages, see:
```
 * CMP: =net-misc/ntp-4.2.8_p15-r6 with net-misc/ntp-4.2.8_p16/image
 *  FILES:-usr/share/man/man8/keygen.8.xz
 *  FILES:-usr/share/man/man8/ntpd.8.xz
 *  FILES:-usr/share/man/man8/ntpdate.8.xz
 *  FILES:-usr/share/man/man8/ntpdc.8.xz
 *  FILES:-usr/share/man/man8/ntpdsim.8.xz
 *  FILES:-usr/share/man/man8/ntpq.8.xz
 *  FILES:-usr/share/man/man8/ntptime.8.xz
 *  FILES:-usr/share/man/man8/ntptrace.8.xz
 *  FILES:-usr/share/man/man8/tickadj.8.xz
 *   SIZE: 18.14MiB -> 18.17MiB, 305 -> 296 files
 * ------> FILES(-9) SIZE(+0.16%)
```

... but man pages remain in man1.
