SLING-3134 - Bundle deployment mechanism does not deploy on the
configured server

With the latest fixes for SLING-3019, we no longer need to use Maven to
deploy bundles. Therefore we now pick up the directory and create a jar
file out of it.

This is faster and less error-prone than building and invoking maven
launch configurations.
