- Allow node bindings to be built if git submodules cannot be checked out
- Made geojsonvt a mason package instead of a git submodule
- Use globally installed mason if it cannot be checked out via git submodules
Sourcing files that set flags bleed into Travis' wrapper script, which
messes with their workflow, e.g. preventing after_failure scripts from
triggering.
These changes fix that:
* Move exported variables from install.sh to setup.sh, so install.sh
doesn't have to be sourced.
* Source setup.sh from run.sh, rather than directly from .travis.yml.
In addition, as a good practice, remove `set -e` etc. from setup.sh,
and add a comment not to add them back. It's the sourcing script's
responsibility to set these flags.
