unix: match ioctl req argument type to libc type

On Solaris, AIX, and zOS, the req argument of ioctl() is a signed int,
not an unsigned long like on other platforms, which means many constants
are negative, causing friction when passing them to a uint argument.
Correct the signature of these functions to pass the req argument as
signed, just like libc.

Fixes golang/go#59030.
