zig additionally looks for lib/std/std.zig 

previously zig would search up directory parents for
lib/zig/std/std.zig. It still does that, but now it also accepts
lib/std/std.zig. This will probably be how we start shipping windows
.zip files, since the extra directory is pointless.

It also means you can run zig binaries from subdirectories of the zig
source tree without lib files being installed.
