Commit 5635dc5142aa ("Enable --transparent mode for docker") made a
little bit of a mess of the Dockerfile and container-entrypoint.sh.
A few issues are, but not limited to; trailing whitespaces, incorrect
indentation, removed final newline, component sortability just to name a
few.
This MR fixes that and cleans up those files again.
One thing not touched was the enable/disablement of `set +e` to exit the
script on error. It is nicer/cleaner to solve this in a different way,
but that adds to much complexity.
While here, make the container architecture and alpine version
configurable, allowing us to build multi-arch images from the CI in the
future.

As per docker guidelines [0] a container should always really have a
consistent entrypoint, without having to override it or do special
tricks.
The behavior should be _identical_ as before, but will no longer trigger
errors because sslh doesn't understand certain parameters (/bin/sh
for example being common). Further more, allows a proper entrypoint for
a CI to work easily with the container as well. Allowing for scenario's
such as `apk add git && sslh --foreground` in your sslh image for example.
E.g. `docker run sslh --help` works though with the default
`--foreground` a bit weirdly, as does `docker run sslh
/bin/sh` or `docker run sslh ls`.
