Split the testsuite into two sub-packages

Small sub-package 'mysql-test' will remain architecture dependent
and will continue to carry all architecture dependent parts of the testsuite.

New huge sub-package 'mysql-test-data' will hold all of the
achitecture independent data and will be built as 'noarch'.

This will save over 1GB of redundant data per each package build.
