Wrong dependencies on maxscale-maxctrl2 package

The maxctrl2 RPM only contains the maxcrl2 binary, and that only depends on libmaxscale-common.so from the maxscale-common RPM.

But it actually has not only the maxscale-common RPM listed as a dependency, but also the maxscale RPM itself.

And as the maxscale RPM lists the older maxscale-mactrl as a weak dependency a simple

yum install maxscale-maxctrl2

will also lead to the older maxscale-maxctrl to be installed, which is most likely not the intended result when someone explicitly requests the newer version to be installed
