capstone: directory install fix

Deals with the issues seen in #34316. Forces a recompile as well, since
anyone who has this package installed from bottle has only text files
in the Cellar, and anyone who has the package installed from source has
/usr/local full of stuff that shouldn’t be directly there.

Closes #34609.
