Makefile: Don't build static build with everything and everything-test

Running the test suite requires building everything, but it seems to be
difficult to build the static version of mdadm now seeing there
is no readily available static udev library.

The test suite doesn't need the static binary so just don't build it
with the everything or everything-test targets.

Leave the mdadm.static and install-static targets in place in case
someone still has a use case for the static binary.
