nproc is a standard util that prints amount of available processes.
-j is a flag that specifies how many cores can be utilized by `make` (default is 1)
-j$(nproc) allows to use all the available machine cores, potentially significantly speeding up completion of CI actions
* Also pass `$*` to `configure` when invoking `ci-build.sh`, so one can
e.g. run `./ci-build.sh --without-xscreensaver`

+ Arch and Debian are run in Docker containers, as openSUSE Tumbleweed.
+ OSX/macOS doesn't use any containers.
* Homebrew is used to fetch all the dependencies.
* The dependencies are declared in the Brewfile.travis file.
+ The travis-build.sh script has been modified to check for the current
OS and the different configure flags has been moved into an array
that'll be looped through instead.
The xscreensaver (for libXScrnSaver) flags has been removed for macOS
as it only makes sense for systems running X11, which macOS doesn't
(usually) do.
+ Some minor shellcheck fixes, too.
Fixes: #1100
