Improve binary-as-unsigned treatment (Bug#34792)

* etc/NEWS:
* src/editfns.c (Fformat, binary_as_unsigned):
Update now that we always have bignums.
(syms_of_editfns) [!defined lisp_h_FIXNUMP]: Remove now-obsolete
code, since lisp_h_FIXNUMP is always defined now.
* test/src/editfns-tests.el (read-large-integer): Simplify,
now that we can assume binary-as-unsigned defaults to nil.
