WASI Example crashes due to unimplemented ImportObj

[helje5]

When running the WASI example, it just crashes due to the import object not being implemented.

Steps I took:

• install Wasmer 1.0, macOS BS Intel, move away .dylib so that the linker picks up the .a (not sure it matters)
• checkout this repository (wasmer-c-api)
• fix the include from the rust path to <wasmer.h>:

  //#include "rust-build/src/wasmer-runtime-c-api/lib/runtime-c-api/wasmer.h"
  #include <wasmer.h>

• compile using:

  cc -I$HOME/.wasmer/include -L$HOME/.wasmer/lib wasmer-wasi-c-api-example.c -o test -lwasmer

• run test

zMBP20:wasmer-c-api helge$  cc -I$HOME/.wasmer/include -L$HOME/.wasmer/lib wasmer-wasi-c-api-example.c -o test -lwasmer
zMBP20:wasmer-c-api helge$ ./test

Sure, Rust, I do that for you:
