Commit message:

syscall: make plan9 Errno implement the error interface

The Errno type was added to plan9 in CL 750680 but without methods,
so it didn't satisfy the error interface. Add Error, Temporary, and
Timeout methods to match all other platforms and the Go 1 API contract
(api/go1.txt's "pkg syscall, method (Errno) Error() string", etc).

And add a test that all platforms have Errno, implementing error.
