Use BlockSpecial in FS_Info module cache (#767842)

Browse source 
The FS_Info cache is loaded from "blkid" output and compares block
special names.  Therefore switch to using BlockSpecial objects so that
comparisons are performed by the major, minor device number instead.

Bug 767842 - File system usage missing when tools report alternate block
             device names
