unix: allow overriding GOOS using GOOS_TARGET in mkpost.go

mkpost.go is platform independent and can in principle be run on a GOOS other than the one we're generating the syscall wrappers for. Allow overriding GOOS by setting GOOS_TARGET, similar to other generator programs in the repo. This e.g. allows testing mkpost.go changes on a different GOOS. Follows CL 256278 which did the same for mksyscall.go Change-Id: Ib99aa5cd266f7d27543cf9433cfb028f367eef63 Reviewed-on: https://go-review.googlesource.com/c/sys/+/484636 Run-TryBot: Tobias Klauser <[email protected]> Auto-Submit: Tobias Klauser <[email protected]> TryBot-Result: Gopher Robot <[email protected]> Reviewed-by: Ian Lance Taylor <[email protected]> Reviewed-by: David Chase <[email protected]>
