e2fsck: add resource tracking for passes 1[b-d] 

On ext2, time tracking for pass1 includes both error detection and
specific type of fs fix-up phase (e.g. block referenced by multiple
inodes).  The multi-reference fix-up phase some time take significant
amount of time to complete.  We would like to track time spent in sub
component of pass1 by having a finer granularity during pass1b through
pass1d phase.
