syscall: add utimensat and use it for UtimesNano on BSD and Solaris

All the BSDs and Solaris support the utimensat syscall, but Darwin
doesn't. Account for that by adding the //sys lines not to
syscall_bsd.go but the individual OS's syscall_*.go files and implement
utimensat on Darwin as just returning ENOSYS, such that UtimesNano will
fall back to use utimes as it currently does unconditionally.

This also adds the previously missing utimensat syscall number for
FreeBSD and Dragonfly.

Fixes #16480
