Ensure stx-openstack tarball builds on Debian

When testing the tarball build (build-helm-charts.sh script) it was
found that the dependency list was not correct and therefore the
generated app was missing python plugins and osh/osh-i charts.
This changes fixes the deb packages dependency lists for both
stx-openstack helm armada and fluxcd.

Also, during the tarball tests it was noticed that the python plugins
package on Debian was wrongly placing the built wheels in a
sub-directory with the app name. That directory is not needed and can
break the correct plugin loading, so it was removed.

TEST PLAN:
PASS - Build stx-openstack-helm on Debian
PASS - Build stx-openstack-helm-fluxcd on Debian
PASS - Build stx-openstack app tarball (armada)
PASS - Upload armada app
PASS - Apply armada app
PASS - Build stx-openstack app tarball (fluxcd)
PASS - Upload fluxcd app
PASS - Apply fluxcd app
