This patch removes calls to getentropy() and BCryptGetRandom() because they
aren't implemented or supported on certain platforms based on the trybot
results I saw. I will try upstreaming a configure script flag soon to replace
this patch file. This patch is safe because it reverts the random number
generation behavior before a recent libxml upstream patch.
