Add special case for Gnocchi detection in run_tests.sh
Add special case for Gnocchi detection in run_tests.sh

Since Gnocchi had to be split into two projects [1], we have an issue
with the project name detection in run_tests.sh, where the project
always gets detected as "gnocchi" instead of "openstack-gnocchi" as
it should be for Pike and earlier releases.

To minimize the risk of breaking other package detection, we are
adding a simple check for the project name.
