obexd should be mentioned in Bluez

[Bruce Dubbs]

From blfs-dev (Xi Ruoyao):

If obexd is not started, some software using Bluetooth
(for example bluetooth-sendto in gnome-bluetooth) will complain
and can not work.

We should mention it in the instruction:

Systemd Obexd Service:
  To start the obexd daemon for user session (to support some Bluetooth
  programs using it), enable the previously installed systemd unit for all
  users by running the following command as root user:

    systemctl enable --global obex

And:

Installed Programs: ... ... mpris-proxy, *obexd*, and rctest

Short Descriptions:
   ...       ...
   obexd     Is the obex D-Bus daemon
   ...       ...

obexd is installed in /usr/libexec. We do not normally list those programs in the book.

We also need to figure out if this is applicable to the sysv side of bluez and address that also.
