Jakub Konka 05fb3e79fe Make std.fs.cwd() return preopen for "." if exists
This commit adds WASI specific impl of `std.fs.cwd()` in which we
emulate the `cwd` behaviour by inquiring the runtime for a "."
preopen if available. This is OK for simple relative ops, but will
not work for any ops which require absolute paths.
