Bug 1315047

+++ This bug was initially created as a clone of Bug #1314753 +++

Description of problem:
Incorrect ExecStop= directive in ejabberd.service resulting in unit stop failing.
The correct directive is:
ExecStop=/usr/bin/bash /usr/bin/ejabberdctl stop

Version-Release number of selected component (if applicable):
ejabberd-14.07-6.fc22.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. systemctl stop ejabberd.service
2. systemctl status ejabberd.service

Actual results:
systemd[1]: Stopping A distributed, fault-tolerant Jabber/XMPP server...
ejabberdctl[3067]: Refusing to render service to dead parents.
systemd[1]: ejabberd.service: Control process exited, code=exited status=127
systemd[1]: Stopped A distributed, fault-tolerant Jabber/XMPP server.
systemd[1]: ejabberd.service: Unit entered failed state.
systemd[1]: ejabberd.service: Failed with result 'exit-code'.

Expected results:
# grep ExecStop= /usr/lib/systemd/system/ejabberd.service 
ExecStop=/usr/bin/bash /usr/bin/ejabberdctl stop

This is easy to fix in Fedora 24, but unfortunately the SRPM does not build anymore on F22 or F23 with this build error:

Compiling /builddir/build/BUILD/ejabberd-14.07/deps/jiffy/c_src/double-conversion/bignum.cc

I will have an F24 fix out shortly, but I don't have time to investigate these build failures this weekend.
