formula_cellar_checks: more granular mismatched_binary_allowlist

[cho-m]

Add support for providing more granular glob patterns via the mismatched_binary_allowlist.json rather than an all-or-nothing option. This allows catching any unwanted binaries in new releases.

The glob patterns are assumed to be relative to the formula's prefix. Patterns are matched using fnmatch with flags for:

• File::FNM_DOTMATCH to allow matching all files with **/*
• File::FNM_EXTGLOB to behave like Dir.glob for {a,b}
• File::FNM_PATHNAME to allow restricting * across directories

The original file format of ["<formula>"] should behave similar to {"<formula>": "**/*"}.

Also some changes to add type signature.
