libblkid: improve whole-disk detection when read /proc/partitions
blkid(8) in high-level mode checks partitions and unpartitioned
whole-disk devices from the file /proc/partitions.
The current heuristic assumes that partition name ends with a digit.
Unfortunately, this is not correct -- for example md0 or nvme0n1 are
whole-disk devices.
This commit uses sysfs_devno_is_wholedisk() to make sure the device is
a partition (according to kernel or DM). It's probably more expensive,
because this way requires more syscalls (to read stuff from /sys etc.).
The patch also adds more information to the blkid(8) man page.
