Modify the add_seeds_stringlist() macro to fix a preprocessor error
When OpenSSL is configured using `--with-rand-seed=devrandom`, the preprocessor
reports the following error
crypto/info.c:104:66: error:
macro "add_seeds_stringlist" passed 3 arguments, but takes just 2
add_seeds_stringlist("random-device", { DEVRANDOM, NULL });
The reason why the preprocessor complains about three arguments being passed
is that according to [1], balanced braces in macro arguments don't prevent the
comma from acting as an argument separator:
3.3 Macro Arguments
...
Parentheses within each argument must balance;
a comma within such parentheses does not end the argument.
However, there is no requirement for square brackets or braces to balance,
and they do not prevent a comma from separating arguments.
Also introduced an iteration pointer `p`, because `dev` is not an lvalue:
crypto/info.c:78:41: error:
lvalue required as increment operand
for (; *dev != NULL; dev++) {
