Fixed overflow at 2G for writing clock frequencies using sysctls.

Reads worked correctly using the IU format.  Writes only supported
signed integers using the CTLTYPE_INT flag.  sysctl(1) parses args for
CTLTYPE_INT using (int)strtol() and has no range checking of course,
so read-write of frequencies larger than INT_MAX always blindly corrupts
the frequency to INT_MAX (2G-1).

This keeps writing of TSC frequencies working up to 4GHz.
