find.1: access ` character portably

When using ` as the Unix shell's command output substitution operator,
use the portable *roff `\(ga` special character escape sequence to
ensure that we really format a grave accent rather than a typographer's
single quotation mark (‘).

* find/find.1: Do the above.
