The C fnctl takes all int parameters, so consistently use int32.
We already used int32 on Darwin.

This requires defining pipe, pipe2, and setNonblock for various platforms.
The new function is currently only used on AIX. It will be used by
later CLs in this series.

In preparation for general faketime support, this renames the existing
nanotime, walltime, and write functions to nanotime1, walltime1, and
write1 and wraps them with trivial Go functions. This will let us
inject different implementations on all platforms when faketime is
enabled.
Updates #30439.

As .init_array section aren't available on AIX, the Go runtime
initialization is made with gcc constructor attribute.
However, as cgo tool is building a binary in order to get imported
C symbols, Go symbols imported for this initilization must be ignored.
-Wl,-berok is mandatory otherwize ld will fail to create this binary,
_rt0_aix_ppc64_lib and runtime_rt0_go aren't defined in runtime/cgo.
These two symbols must also be ignored when creating _cgo_import.go.

AIX doesn't have HWCAP/HWCAP2 variables like Linux. Therefore, it relies on
getsystemcfg syscall which can provide some information about the CPU.
