[PATCH rhel6-branch] Ignore --device=ibft in stage 2 kickstart handling (#638131)

[Radek Vykydal <rvykydal redhat com>]

Stage 2 can't handle "ibft" value, it is used meaningfuly only
in loader kickstart where the device would also be activated.

Related: rhbz#638131

Port of modified vpodzimek's patch for master. Tested.
