LOG: [PGO][test] Specify exact match for check labels (#117376)

Some check labels in the basic.ll test are simply f[1-3], which matches
all cases where the function entry is hot, cold, or uncategorized. Since
the actual test results for each label have mixed cases, the current
labels can be considered ambiguous.

This patch specifies exact matches for each label to ensure more precise
validation and to prevent potential regressions in the future.
