3742: Fixed "core" Docker image to allow x86_32 building, updated documenta… r=mergify[bot] a=vparres ## What type of PR? bugfix / documentation ## What does this PR do? Allow building a i686 linux image on a amd64 machine by switching from `uname -m` architecture detection to `apk --print-arch` to better reflect the binary distribution architecture instead of the current Kernel architecture and adding the rust toolchain in dependencies. Also updated the documentation to mention SSE4.2 requirement and reference to the mailu issue i opened earlier. I didn't wanted to add any kind of automated building changes in this PR before discussions, as it may add unneeded pressure on mailu pipelines. To solve the issue with rspamd mentioned in #3713, only the `base` and the `antispam` images needs to be rebuilt on i686, and it can be done locally if needed. ### Related issue(s) - closes #3713 ## Prerequisites Before we can consider review and merge, please make sure the following list is done and checked.
