go.sys: copy files from syscall package to go.sys/{plan9,windows,unix}
This CL copies to each package of go.sys the files from syscall it will need.
Different directories have different files, but these:
mkall.sh
str.go
syscall.go
mksyscall.pl
race.go
race0.go
syscall_test.go
are copied to all three.
No changes yet, these are just copies. They are not ready to use yet:
package names are wrong, for starters. But this clean copy will make
it easier to follow the changes as the packages are enabled.
