Check and fix on custom env module name

[da1suk8]

In dynamic link, names other than env are judged as module to be used in dynamic link.
Thus, for example, wasi_snapshot_preview1.fd_filestat_get generated by wasm32-wasi is judged as a module used in dynamic link.

If it is necessary to separate the dynamic link module from the other modules, make the necessary modifications.
