Unlike upstream, skip it also for DHCP.
Disable RAND_status also in non-threaded builds. DHCP is built without
threads and should not check RAND_status on dns library initialization.
Lack of entropy is possible state for dhclient, but it must not fail
even in this case. Because DHCP itself does not require custom random
generator, leave default RAND_OpenSSL configured. It should help TLS
connection to LDAP in single DHCP binary, while keeping secure random
data if needed.
Resolves: #1663318
(modified upstream commit 8a98277811ea50035ff37b744fa3dc5b75bee099)
dhclient can terminate if not enough entropy, but it never requires
random data. On a new virtual machine, lack of entropy can be common.
Ensure it does not prevent DHCP client assigning an IP address.
