vaultwarden compiled on Alpine Linux segfaults without "RUSTFLAGS=-C target-feature=-crt-static"

[DerVerruckteFuchs]

I've attempted to build vaultwarden on Alpine Linux 3.15 and 3.16, and the resulting binary segfaults when trying to run it. It seems to be a build environment issue with OpenSSL. The build environment fix (using RUSTFLAGS=-C target-feature=-crt-static) from the link worked for me. I used env RUSTFLAGS=-C target-feature=-crt-static cargo build..., and I have a build that runs successfully. It would probably be a good idea to set this somewhere for Alpine Linux builds.

We do not use alpine as a build environment, so no need to add this. Maybe adding it to the wiki is an option.
