cdrom_id: add data track count for bad virtual drive implementations

Browse Source 
/# /lib/udev/cdrom_id --debug /dev/sr0
probing: '/dev/sr0'
INQUIRY: [AMI     ][Virtual CDROM   ][1.00]
GET CONFIGURATION failed with SK=5h/ASC=20h/ACQ=00h
drive is pre-MMC2 and does not support 46h get configuration command
trying to work around the problem
READ DISC INFORMATION failed with SK=5h/ASC=20h/ACQ=00h
no current profile, but disc is present; assuming CD-ROM
READ TOC: len: 12, start track: 1, end track: 1
last track 1 starts at block 0
READ DISC INFORMATION failed with SK=5h/ASC=20h/ACQ=00h
ID_CDROM=1
ID_CDROM_MEDIA=1
ID_CDROM_MEDIA_CD=1

What is missing here is ID_CDROM_MEDIA_TRACK_COUNT_DATA to trigger
blkid in /lib/udev/rules.d/60-persistent-storage.rules

KERNEL=="sr*", ENV{DISK_EJECT_REQUEST}!="?*",
	ENV{ID_CDROM_MEDIA_TRACK_COUNT_DATA}=="?*",
	ENV{ID_CDROM_MEDIA_SESSION_LAST_OFFSET}=="", \
		  IMPORT{builtin}="blkid --noraid"
