unix: add linux constants and types for PPS devices ioctl's

After trying to implement Pulse Per Second devices
in go, I found that the ioctl values and structs
where not in the unix package yet:

~# strace ppstest /dev/pps0 |& grep ioctl
ioctl(3, PPS_GETPARAMS, 0xbee63b18)     = 0
ioctl(3, PPS_GETCAP, 0xbee63b84)        = 0
ioctl(3, PPS_GETPARAMS, 0xbee63b18)     = 0
ioctl(3, PPS_SETPARAMS, 0xbee63b18)     = 0
ioctl(3, PPS_FETCH, 0xbee63b00)         = 0
ioctl(3, PPS_FETCH, 0xbee63b00)         = 0
ioctl(3, PPS_FETCH, 0xbee63b00)         = 0
ioctl(3, PPS_FETCH, 0xbee63b00)         = 0
ioctl(3, PPS_FETCH, 0xbee63b00)         = 0

This commit should add them.
