Use matrix and Makefile to build both images in the same workflow.
Kanidmd image remove muslc version and come back to SUSE version because
performance problems.
Also fix a typo bug with kanidmd image build on CI.
- Change base builder image to `ekidd/rust-musl-builder` for create static
binaries.
- Add two flavours: alpine and stand alone binary.
- Add makefile commands for build, test and push kanidmd images and
refactor previous code.
- Add missing things to `.dockerignore`.
- Refactor CI to use Makefile.
Add `libsqlite3-sys` crate to avoid sqlite3 missmatching version.
From [https://lib.rs/crates/libsqlite3-sys](https://lib.rs/crates/libsqlite3-sys)
> If you use the bundled feature, libsqlite3-sys will use the cc crate to compile SQLite from source and link against that. This source is embedded in the libsqlite3-sys crate and is currently SQLite 3.30.1 (as of rusqlite 0.21.0 / libsqlite3-sys 0.17.0). This is probably the simplest solution to any build problems.
Remove sqlite OS packages dependencies for build.
Also, we fix a format error to allow CI tests to pass again.
