Subject: [PATCH] Free old cookie value to prevent a memory leak

This keeps the old behaviour of overriding the cookie. This may not me
correct as the code looks like it reads the cookie from the srpm when
doing rpmbuild --rebuild for the purpose of preserving it. Otoh the
current behaviour with overriding it even in this case has been around
for years. This whole cookie business seems to have some other issues,
too, and needs further investigation. Here we are only trying to fix the
memory leak.
