[LTP] [PATCH v3 2/3] lib/tst_test.c: Update result counters when calling tst_brk()

[Xiao Yang]

1) Catch and report the TFAIL exit status of child process.
2) Only update result counters in library process and main test
   process because the exit status of child can be reported by
   main test process.
3) Print TCONF message and increase skipped when calling tst_brk(TCONF).
   Print TBROK message and increase broken when calling tst_brk(TBROK).
   Print TFAIL message and increase failed when calling tst_brk(TFAIL).
4) Remove duplicate update_results() in run_tcases_per_fs().

Fixes: #408
