iscsitarget: Remove recipe as it is no longer supported to build with linux kernel >= 4.14

The upstream iscsitarget source does not have support to build
with Linux kernel >= 4.14, as the "struct bio" members has been updated
in the linux kernel v4.14 source. Requires major code change in
iscsitarget to support building later versions of Linux kernel.

The Linux SCSI target framework (tgt) recipe present in meta-openstack
layer, can be used as a substitute to iscsitarget recipe and works fine
in our testing.
