bin/brew: enforce UTF-8 locale

Browse Source 
Everyone should be using a UTF-8 locale nowadays. Not using one causes
issues like `brew doctor` failing while checking symbolic links that
point at file names with non-ASCII characters, since OS X always uses
Unicode for the file system.

Rely on `locale charmap` to detect the currently selected encoding and
if that's not UTF-8, override the user's choice (if any) by setting
`LC_ALL` to `en_US.UTF-8`, the assumption being that every system has a
usable `en_US.UTF-8` locale installed.

Fixes Homebrew/homebrew#44744.
Closes Homebrew/homebrew#47247.
