Make tests independent of proj-datumgrid

Fixes #1984

- Copy BETA2007.gsb, MD, alaska, conus, ntf_r93.gsb, ntv1_can.dat grids
  from proj-datumgrid to data/tests.
- Replace a couple uses of nzgd2kgrid0005.gsb in tests by ntf_r93.gsb
- Add downsampled/subsetted versions of egm96_15.gtx as tests/egm96_15_downsampled.gtx
  and ntv2_0.gsb as tests/ntv2_0_downsampled.gsb
  This results in a few changes in expected results
- Simpify travis/install.sh due to less configurations to test

This results in a hopefully acceptable increase of the proj-X.Y.Z.tar.gz
from 2.9 to 5.3 MB
