Regexp-quote strings of avy-goto-char* functions.

Before this commit, avy-goto-char with char ^ would inf-loop because the
resulting string "^" is treated as a regular expressions.  However, with
the avy-goto-char* function, the char should be treated literally.  For
example, in Clojure ^:foo is treated as metadata annotation and thus ^
is a likely jump target.
