Crypt Keeper a2ddb04fdb wasi: enforce EPERM on malformed paths (#1266) ...

It seems WASI now forbids root and relative paths on the at file descriptor and returns EPERM otherwise. This enforces the following:

* require EPERM when you escape a directory (../)
* require EPERM if you add a leading slash (absolute path)
* require ENOENT if you add a trailing slash to a file
* require success if you add a trailing slash to a directory
