Add iscsi-initiator-utils recipe

This patch instroduces iscsi-initiator-utils bitbake
for building iscsi initiator open-iscsi version 2.0-873

This bitbake iscsi-initiator-utils is based on openembedded:

git://github.com/DFE/HIPOS/meta-hidav/recipes-connectivity/open-iscsi

* Add hook do_configure for utils/open-isns to support cross compiling.
* Follow fedora to install apps to /sbin but not /usr/sbin, to change init.d
  file to iscsid and change the script's log_daemon_msg to echo as it is
  not defined by lsb/init-functions.
* Completely override default install as bugs in original source's Makefile
* Add Fedora patch for changing app's state files from /etc/iscsi
  to /var/lib/iscsi
* Add Fedora patch "dont-use-static".
