Support all DB's for Alpine and Debian

- Using my own rust-musl build containers we now support all database
types for both Debian and Alpine.
- Added new Alpine containers for armv6 and arm64/aarch64
- The Debian builds can also be done wihout dpkg magic stuff, probably
some fixes in Rust regarding linking (Or maybe OpenSSL or Diesel), in
any case, it works now without hacking dpkg and apt.
- Updated toolchain and crates
