This patch fixes some thing which cause problems started up
Samba. One of the changes prevents gnutls from using the new
getrandom() syscall which blocks for a painfully long time.
This reduces startup times from 90 seconds to 3 seconds.
The other change alters the library path for samba to
include /usr/lib/samba.
