Subject: [PATCH] Add support for arm64 builds

Allow building Rocket.Chat for arm64 platform.
Changes made to the Dockerfile:
- Changed base image to provide a higher version of glibc.
- Check architecture compliance and store the result in env variable.
- Build some packages from sources as they do not provide arm64 versions.
Build tested on x86 and arm64.
