md: select BLOCK_LEGACY_AUTOLOAD

commit 6c0f5898836c05c6d850a750ed7940ba29e4e6c5 upstream.

When BLOCK_LEGACY_AUTOLOAD is not enable, mdadm is not able to
activate new arrays unless "CREATE names=yes" appears in
mdadm.conf

As this is a regression we need to always enable BLOCK_LEGACY_AUTOLOAD
for when MD is selected - at least until mdadm is updated and the
updates widely available.
