syscall: support Getwd on all BSDs
All supported BSDs provide the SYS___GETCWD syscall which can be used to
implement syscall.Getwd. With this change os.Getwd can use a single
syscall instead of falling back to the current kludge solution on the
BSDs.
This doesn't add any new exported functions to the frozen syscall
package, only ImplementsGetwd changes to true for dragonfly, freebsd,
netbsd and openbsd.
As suggested by Ian, this follows CL 83755 which did the same for
golang.org/x/sys/unix.
Also, an entry for netbsd/arm is added to mkall.sh which was used to
generate the syscall wrappers there.
