unix: allow overriding GOOS using GOOS_TARGET in mksyscall.go
The syscall wrapper generator utility 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.
Also remove the unused GOARCH_TARGET override in the same file.
