Allow dired to invoke secondary browser

'browse-url-of-dired-file' always invokes the primary browser, but
sometimes it's handy to call a different browser, which is why
'browse-url-secondary-browser-function' exists.

* lisp/net/browse-url.el (browse-url-of-dired-file): Call
'browse-url-secondary-browser-function' when invoked with a prefix
argument.
