Update RAND_METHOD definition in man page

The `add` and `seed` callbacks were changed to return `int` instead of
`void` in b6dcdbfc94c482f6c15ba725754fc9e827e41851 (first included in
tag OpenSSL_1_1_0-pre1).

The `add` callback was changed to take a `double` instead of an `int`
in 853f757ecea74a271a7c5cdee3f3b5fe0d3ae863.
