UBI now supports the image sequence number feature which
prevents UBI from mistakingly accepting half-written images,
if the image was written on top of an older image. Support
this feature in ubinize and make it pick a random
number for the UBI image sequence number.

Not-so-old linux kernel like 2.6.29 do already have "/sys/class/mtd/mtdX"
directories, while very old kernels do not. But in 2.6.29 these
directories do not contain any information.
Anyway, the logic in libmtd which checked whether the system
supports sysfs was broken, because it assumed that old systems
do not even have "/sys/class/mtd/" directory.
Fix this problem by checking for "/sys/class/mtd/mtdX/name". If this
is present - the system really has sysfs support.
This patch also adds an extra print to libmtd.
