QStorageInfo/Linux: resolve non-existent devices via /dev/block

On systems with very simple boot sequences, the kernel will create a
device called /dev/root and use that to mount the root filesystem.
However, that doesn't actually exist in /dev and could cause
confusion. So we try to resolve using /dev/block if the /dev entry does
not exist but udev is in use (udevd has the string "/dev/%s/%u:%u").

[ChangeLog][QtCore][QStorageInfo] Improved discovery of device nodes on
Linux if the /dev entry was renamed after the filesystem was mounted and
udev is in use.

Fixes: QTBUG-81464
