Changes since 1.6: +51 -16 lines

Update to cdpack-1.9.  This version teaches cdpack how to add packages
ending in .tbz as well as .tgz.  Should address the problem reported
in PR pkg/40515.  I am explicitly not using the mk.conf settings
for PKG_SUFX though because at run time we may or may not have a valid
mk.conf on hand that corresponds to how the packages were built.
