[PATCH] t4014: strengthen search patterns

[Kaartic Sivaraam <kaarticsivaraam91196@gmail.com>]

The regex patterns for some failing test cases were a bit loose
giving way for a few incorrect outputs being accepted as correct
outputs.

To avoid such incorrect outputs from being flagged as correct ones
use fixed string matches when possible and strengthen regex when
it's not.
