crypto: api - Disallow cryptomgr as a module if algorithms are built-in
If we have at least one algorithm built-in then it no longer makes
sense to have the testing framework, and hence cryptomgr to be a
module. It should be either on or off, i.e., built-in or disabled.
This just happens to stop a potential runaway modprobe loop that
seems to trigger on at least one distro.
With fixes from Evgeniy Polyakov.
