IllinoisGRMHD's magnetizedTOV.par test uses too much memory

It requests ~1GB of memory which is too much for a test case I think.

Simple changes to reduce memory consumption is setting

CoordBase::dx   =   1.5
CoordBase::dy   =   1.5
CoordBase::dz   =   1.5

CarpetRegrid2::num_levels_1 = 2

down from

CoordBase::dx   =   1.0
CoordBase::dy   =   1.0
CoordBase::dz   =   1.0

CarpetRegrid2::num_levels_1 = 4

which should bring memory consumption down to ~150MB which is much better eg on the Jenkins test slaves.
