cat: raise unless object is formulae

Browse Source 
Until a point in time when the Cask/Homebrew codebases are harmonised a little
more it probably makes sense to refuse to `cat` Casks. Right now the Homebrew
codebase is only minimally aware of what a Cask is.

Fixes Homebrew/homebrew#45300.
Fixes Homebrew/homebrew#44630.

Closes Homebrew/homebrew#45302.
