wasm: Fix build with wasmtime 27.0.0
Wasmtime 27.0.0 adjusted the C API to start flowing through the
directory and file permission bits of the underlying rust
wasi_config_preopen_dir() implementation.
The directory permissions control whether a directory is read-only or
whether you can create/modify files within.
You always need at least WASMTIME_WASI_DIR_PERMS_READ.
The file permissions control whether you can read or read/write files.
WASMTIME_WASI_FILE_PERMS_WRITE seems to imply
WASMTIME_WASI_FILE_PERMS_READ (but we add both just to make it clear
what we want)
[ Permissions tweak and commit message - Andrew ]
