LOG: [PAC][clang][test] Fix incorrect usage of `-NOT` suffix for FileCheck (#212445)

Previously, `-NOT` checks were not doing what was intended: checking
that given strings are not present within the same line where other
patterns are confirmed present by other checks. `-NOT` semantics is
checking pattern absense in between other checks, not total absense.

This patch makes use of `--implicit-check-not` instead for this purpose.
