Fix references to prefix_wasm_api

[keithmattix]

References to include/wasm.h changed to crates/c-api/include/wasm.h, so the prefixed api output needs to change as well. Fixes #418

[PiotrSikora]

@keithmattix The change looks fine, but could you please confirm that it fixes the build and tests with --define=engine=multi? The CI doesn't check that configuration due to time constraints. Thanks!

@PiotrSikora I at least got past the error @wbpcode reported in #418, but am now dealing with wasmedge failures. I haven't been able to get past them yet, but will keep trying. If @wbpcode has a working setup, they may be able to confirm before I can. I think the wasmedge compilation step is considering all of my warnings as errors and I'm trying to find where I can disable that

[PiotrSikora]

@wbpcode @mpwarres could you verify if this fixes the multi-engine builds?

@PiotrSikora FWIW, I faced the same problem as in #418 and arrived to the same fix as @keithmattix did. I checked that it addresses the problem for me and the command from #418 works for me now:

bazel build --define=engine=multi :lib

Would it count as verification enough to merge this PR?

Sorry for the delay and thanks for the nudge, this fell through the cracks. Thanks for the fix!
