Builds fail when built with musl

[odrling]

Builds fail when built with musl libc while calling the karaberus executable to generate the openapi spec.
The executable segfaults on startup due to golang/go#13492.
There is apparently no known workaround.

Building with c-archive has been the most stable way I've found to build the project with meson, because then the final executable is just a C program that links to our dependencies and the karaberus go library which is fairly easy and straightforward.

I was slightly surprised that the cli args "just worked" when building with c-archive, and it's sad that we now pay the cost in portability.

Quick Dockerfile/Containerfile to reproduce the issue on Alpine:

FROM alpine
RUN apk add go gcc npm meson musl-dev libass-dev ffmpeg-dev git
RUN git clone https://github.com/Japan7/karaberus /karaberus
RUN meson setup /build /karaberus -Dtest=false -Ds3_tests=disabled && meson compile -C /build
