Tests included in the distribution

[pmav99]

It seems that some tests get included in the distribution.

$ find ./dist.x86_64-pc-linux-gnu -name *test*

./scripts/db.test
./gui/icons/grass/shortest-distance.png
./gui/wxpython/mapdisp/test_mapdisp.py
./gui/wxpython/mapdisp/__pycache__/test_mapdisp.cpython-37.pyc
./docs/man/man1/test.r3flow.1
./docs/man/man1/topic_unit_test.1
./docs/man/man1/test.raster3d.lib.1
./docs/man/man1/db.test.1
./docs/html/g_parser_test.png
./docs/html/icons/shortest-distance.png
./docs/html/db.test.html
./docs/html/v_to_rast3_test.png
./docs/html/test.raster3d.lib.html
./docs/html/topic_unit_test.html
./docs/html/test.r3flow.html
./etc/db.test
./etc/db.test/test1
./etc/python/grass/gunittest
./etc/python/grass/temporal/unit_tests.py
./etc/python/grass/temporal/__pycache__/unit_tests.cpython-37.pyc
./etc/python/grass/pygrass/tests
./bin/test.r3flow
./bin/test.raster3d.lib

The previous list obviously contains false positives. These seem to be the ones that actually need to be removed:

./gui/wxpython/mapdisp/test_mapdisp.py
./etc/db.test/test1
./etc/python/grass/temporal/unit_tests.py
./etc/python/grass/pygrass/tests
./bin/test.r3flow
./bin/test.raster3d.lib
