Remove uneeded build tasks in Makefile

- Since removing the jboss/application server bits we no longer need
  those build tasks in the Makefile.
- Remove building gpgkeys entirely since it is not referenced anywhere in
  the code.
- Update the creation of tarballs to exclude-vcs directories such as .git, .bzr,
  etc.
- Move build tasks from deb-unsign to deb because its less to type and still
  properly explains what the task is.
