tests: net: limit tests to boards with enough memory to build them

A number of the network tests have minimal memory requirements that not
all boards are able to meet.  Add in those memory requirements so we
don't attempt to build these tests for those platforms.  Utilized the
frdm_kl25z (with 16K of memory) and cc2650_sensortag (with 20K) to test
the limits.
