KVM test: Make physical_resources_check cope with qemu change on 'info block'

New qemu upstream versions report block info like this:

(monitor humanmonitor1) Sending command 'info block'
(monitor humanmonitor1) Response to 'info block'
(monitor humanmonitor1)    virtio0: removable=0 file=/tmp/kvm_autotest_root/images/rhel6-64.qcow2 ro=0 drv=qcow2 encrypted=0
(monitor humanmonitor1)    ide1-cd0: removable=1 locked=0 [not inserted]
(monitor humanmonitor1)    floppy0: removable=1 locked=0 [not inserted]
(monitor humanmonitor1)    sd0: removable=1 locked=0 [not inserted]

While older versions report like this:

(monitor humanmonitor1) Sending command 'info block'
(monitor humanmonitor1) Response to 'info block'
(monitor humanmonitor1)    virtio0: type=hd removable=0 file=/tmp/kvm_autotest_root/images/rhel6-64.qcow2 ro=0 drv=qcow2 encrypted=0
(monitor humanmonitor1)    ide1-cd0: type=cdrom removable=1 locked=0 [not inserted]
(monitor humanmonitor1)    floppy0: type=floppy removable=1 locked=0 [not inserted]
(monitor humanmonitor1)    sd0: type=floppy removable=1 locked=0 [not inserted]

The type field was removed, as it wasn't reliable. So for searching for
hard drives, look for the disk image name rather than the type tags.
