benchmark,lib,test,tools: remove unneeded . escape

The `.` character does not need to be escaped when it appears inside a
regular expression character class. This removes instances of
unnecessary escapes of the `.` character.

This also removes a few unnecessary escapes of the `(` and `)`
characters within character classes too.
