Cope with cross-compiling when checking for a random-number source.

Commit 16f96c7 neglected to consider the possibility of cross-compiling, causing cross-compiles to fail at the configure stage unless you'd selected --with-openssl. Since we're now more or less assuming that /dev/urandom is available everywhere, it seems reasonable to assume that the cross-compile target has it too, rather than failing. Per complaint from Vincas Dargis. Back-patch to v14 where this came in. Discussion: https://postgr.es/m/0dc14a31-acaf-8cae-0df4-a87339b22bd9@gmail.com
