net-im/ejabberd: Bump version

Remove obsolete flags. 'ssl' flag is removed because TLS support is not
optional. 'tools' flag is temporarily removed because of problematic
dependency. It may be restored in the future, although it just controls
whether development tools should be installed.

Debundle ejabberd dependencies. Use system rebar instead of bundled one.

Access epam binary via wrapper with ejabberd user ownership. Fix epam
binary localisation.

Correct path to captcha command.

Skip installing docs from Makefile, because this only install COPYING.

Restrict test because test suite doesn't work out of the box. It needs
database set up first.

Rebase ejabberctl patch.

Refactor ebuild and bump EAPI to 6.

Correct funny capitalization in description.

Package-Manager: portage-2.3.0_rc1
