[PATCH anaconda-dracut] Fix ksdevice=<MAC> - instead of renaming the device to ksdev0 just use it

ksdevice option doesn't work in f17 and f18.
It used to specify which network device to activate in early stage of
installation, eg. to fetch kickstart or installation image.
In F17 and F18 the device should be specified by dracut option ip=
Mapping of ksdevice options from loader to dracut options used in
F17 and F18:
- ksdevice missing (and network is required)
loader: user was asked in UI in case of more devices present
dracut: activates all devices if not specified
- ksdevice=eth0
loader: eth0 is activated
dracut: specify device in ip=, eg
ip=eth0:dhcp
ip=10.34.39.44::10.34.39.254:255.255.255.0::eth0:none
- ksdevice=00:12:34:56:78:9a
loader: device with MAC address is activated
dracut: We translate it to ifname=ksdev0:00:12:34:56:78:9a which renames
the device.
It is possible to use BOOTIF=00-12-34-56-78-9a, which this patch
does.
- ksdevice=link
loader: first device with link found is activated
dracut: no way to achive this (activate single unspecified device)?
- ksdevice=ibft
loader: activate devcie configrued in iBFT
dracut: use ip=ibft option
