We do not need tox_install.sh, pip can handle constraints itself
and install the project correctly. Thus update tox.ini and remove
the now obsolete tools/tox_install.sh file.
This follows https://review.openstack.org/#/c/508061 to remove
tools/tox_install.sh.

murano-pkg-check is now present in upper-constraints.txt, so install command
should be replaced with tools/tox_install.sh
