Failure to remove legacy poetry version in 5.0.6-0 rpm rockstor#2782

Add legacy poetry install path to avoid failing its uninstall.
Without this additional path, when build.sh is run from within
RPM's constrained %posttrans scriptlet, we fail to find and
uninstall our prior 1.1.15 poetry version. This leads to having
both poetry 1.1.15 (via upstream installer) and our new pipx
installed poetry 1.7.1.
