[pkg-php-pear] Fixing FTBFS in symfony before the PHP migration

According to the changelog, the goal of this change may be to fix a
security issue:

 * security #17359 do not ship with a custom rng implementation (xabbuh,
fabpot)

I don’t know the security implications of this fix, but it seems important
enough to upstream to backport it to all currently maintained branches.
Can you have a look at it, and eventually propose a patch for Jessie if
it’s worth it?

Regards

David
