test: Update travis build to include a basic klippy host test

Move the travis installation steps from the travis-build.sh script to
a new script (scripts/travis-install.sh).  Move the travis-build.sh
script to the scripts/ directory as well.

The data dictionaries built in the compile tests are useful during
host software testing, so run all the compile tests sequentially in a
single VM and save the data dictionaries after each build.  Also,
build all the config files found in the test/configs/ directory.

Create the python virtualenv environment during the install phase and
invoke the klippy.py host software in the build phase to perform a
basic host software sanity check.
