Tobias Klauser 4d22bbb62b unix: remove darwin support from mksysnum.go 
Since CL 250437 this package no longer supports non-libc, direct
syscalls on darwin. Thus support for generating zsysnum_*.go files on
darwin can be removed from the generating mksysnum.go program.

Tobias Klauser 9d91bd6205 unix: implement Getwd using getcwd from libSystem on darwin 
Directly wrap the getcwd implementation provided by libSystem.dylib on
darwin and use it to implement Getwd like on the BSDs. This allows to
drop the custom implementation using getAttrList and to merge the
implementation of Getwd for darwin and the BSDs in syscall_bsd.go.

Tobias Klauser cb7fb32132 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.

Getdirentries is implemented with the __getdirentries64 function
in libSystem.dylib on darwin/{386,amd64}. That function can't be used in
an app store application.

Implement Getdirentries using the underlying
fdopendir/readdir_r/closedir for Go 1.13. The simulation isn't faithful,
and could be slow, but it should handle common cases.

For Go 1.12, fall back to raw syscalls since syscall.syscallPtr needed
to use fdopendir from libSystem.dylib is not available.

Follow CL 168479 and CL 170892 which did the same for syscall in the
