Install baseline bandit

this version contains git and fixes the error:
[  ERROR ] Git not available, reinstall with baseline extra

This is the same fix as in atomic-reactor repo containerbuildsystem/atomic-reactor@1f46fbe

Also the quotes are neccessary to fix the shellcheck error:
In ./test.sh line 86:
  $RUN $PIP install bandit[baseline]
