[PIPE2D-295] Fix use of GitHub API

We often get in Travis:

...
scons: done building targets.

The command '/bin/bash -lc . ${LSST_DIR}/loadLSST.bash  && setup lsst_distrib  && export -f setup  && . /opt/rh/devtoolset-${DEVTOOLSET}/enable  && ${PFS_DIR}/build_pfs.sh $INSTALL_PFS_ARGS -t current  && ( find ${PFS_DIR} -exec strip --strip-unneeded --preserve-dates {} +       > /dev/null 2>&1 || true )  && ( find ${PFS_DIR} -maxdepth 5 -name tests -type d -exec rm -rf {} +       > /dev/null 2>&1 || true )  && ( find ${PFS_DIR} -maxdepth 5 -path "*doc/html" -type d -exec rm -rf {} +       > /dev/null 2>&1 || true )  && ( find ${PFS_DIR} -maxdepth 5 -name src -type d -exec rm -rf {} +       > /dev/null 2>&1 || true )' returned a non-zero code: 22

Note the 403 Forbidden, which is coming from a curl command using the GitHub API. I believe we are exceeding a rate limit in the GitHub API (possibly a limit shared by everyone on Travis?). Instead, we can dump the use of the GitHub API and just download the repo with git.
