Only build embedded if explicitly requested and possible.

autotest option now no longer turn on embedded server build.

This reduces the binary distribution size significantly, and there are no
autotest suites testing embedded server anyway.

In newer releases the option, WITH_EMBEDDED_SERVER, is removed.

The compiler-cluster script checks if libmysqld directory exists in source.
If not it assumed that there is no WITH_EMBEDDED_SERVER option, and none
is passed to cmake which would otherwise give a warning.
