WASM_STANDALONE: Errno 63 (Out of stream resources) at fopen call

**Error description:**
I'm trying to build a standalone WASM module which is reading from a file by using WASI.
The compilation is done by running the following command:
```
emcc filetest.c -o filetest.wasm --no-entry -s ERROR_ON_UNDEFINED_SYMBOLS=0
```
The compilation works fine and succeeds without an error.

I'm using wasmtime in order to run the module:
```
wasmtime filetest.wasm --dir . --invoke filetest
```
In my working directory, there is a file 'test.txt', which only contains one line with the content "test".
Running the WASM module by using the previously mentioned command, I'm getting the following output:
```
Fopen failed, errno = 63
```
Looking up the meaning of errno 63, there seems to be an issue with stream resources:
```
ENOSR 63 Out of streams resources
```

I also activated the wasmtime WASI trace logging by setting the environment variable *RUST_LOG* to *wasi_common=trace*. Running the wasmtime command now prints the following output:
```
TRACE wasi_common::snapshots::preview_1::wasi_snapshot_preview1 > wiggle abi; module="wasi_snapshot_preview1" function="fd_write"
TRACE wasi_common::snapshots::preview_1::wasi_snapshot_preview1 > fd=Fd(1) iovs=*guest 0x500e40/2
Fopen failed, errno = 63 TRACE wasi_common::snapshots::preview_1::wasi_snapshot_preview1 > result=Ok(24)
TRACE wasi_common::snapshots::preview_1::wasi_snapshot_preview1 > wiggle abi; module="wasi_snapshot_preview1" function="proc_exit"
TRACE wasi_common::snapshots::preview_1::wasi_snapshot_preview1 > rval=1
TRACE wasi_common::snapshots::preview_1::wasi_snapshot_preview1 > result=I32Exit(1)
```
This log shows that no open- or read-call was performed. There is only a fd_write-call, that prints the error message to the stdout file descriptor.

What is the reason behind this error and what can I do in order to get my example running?

**Example code:**
```
#include
#include
#include
#include

EMSCRIPTEN_KEEPALIVE void filetest() {
FILE *handle = fopen("test.txt", "r");

if (handle == NULL) {
printf("Fopen failed, errno = %d", errno);
exit(EXIT_FAILURE);
}

fclose(handle);
}
```
