Subject: FindMatlab: Fix Matlab_LIBRARIES for MCR

In commit bda5e2ac8f (FindMatlab: Only include engine and dataarray
libraries if they are found, 2020-12-11, v3.20.0-rc1~297^2~1) we fixed
the imported target to contain optional libraries only if they are
found.  Do the same for `Matlab_LIBRARIES`.
