CI: let rpmbuild accept PXF's Cloudberry RUNPATH on Rocky 10 - #181

RHEL/Rocky 10 added check-rpaths to rpmbuild's %install post-processing (RHEL 8/9 never run it). It flags any absolute RUNPATH outside the system library directories as invalid (0x0002), so the Rocky 10 PXF RPM build fails on gpextable/pxf.so and fdw/pxf_fdw.so, which point at /usr/local/cloudberry-db/lib on purpose to load the Cloudberry libraries.

Set QA_RPATHS=0x0002 for the PXF build, which tolerates exactly that class and keeps the other rpath checks in force. ci/docker/pxf-cbdb-dev /rocky10/script/build_cloudberry_rpm.sh works around the same check for the Cloudberry RPM.
