[linter] add exceptions to include guards and file name linters

Summary:
an upcoming backport (https://github.com/bitcoin/bitcoin/pull/17009/commits/bebb637472d0469037a9f438572fc71db4236d97) regarding Fuzz harnesses adds a header file from the Chromium project. this lets us add exceptions as to avoid modifying it

Depends on D6741

Test Plan:

cd src
mv hash.h Hash.h
vim Hash.h

run :%s/BITCOIN_HASH_H/TEST_LINTER_H/g and :wq!

git add Hash.h

arc lint

linter yells at you

add "Hash.h" to the EXCEPTIONS array in both FileNameLinter.php and IncludeGuardLinter.php

arc lint

linter no longer yells at you
