[Crash-utility] [PATCH v4 03/12] "whatis -m": fix duplications in the output

[Alexey Makhalov]

"whatis -m" output started to generate duplicated results after GDB update:

crash> whatis -m mm_struct
SIZE  TYPE
   16  tlb_state
...
  256  linux_binprm
  2752  rq
  2752  rq  <<-- duplicated
  2752  rq
  2752  rq
  2752  rq
  4048  task_struct

It was caused by incorrect string comparisons.
Use strcmp for full string comparison instead of just string pointers
comparison.
