unknown file type: botan-test.bc when converting tests to wasm

[radekgs]

Following the instructions on https://botan.randombit.net/handbook/building.html#emscripten-webassembly, after successfully compiling the framework and trying to folllow the second step of converting the tests to wasm I get the following error:

Sorry for the long waiting time, @radekgs. Admittedly, we're no experts on WASM (, yet). It would be great if you could try out the patch we provided in #2864 and verify that this helps.
