Description of problem:
system-profile-transition rpm should avoid using advanced rpmlib capabilities. hammer import content-host command shows build instruction how to create on Sat6 an rpm for systems transition. Built rpm "system-profile-transition-*.rpm" requires some advanced rpmlib capabilities!
Just imagine situation Sat6 is on RHEL6 machine, therefore built rpm will require rpmlib capabilities like FileDigests, PayloadIsXz, according to building OS. These capabilities cannot be handled on RHEL5. And the rpm is going to be installed on Sat5 machine, which can have various OSes. The problem can arise if build_OS > install_OS.

Version-Release number of selected component (if applicable):
rubygem-hammer_cli_import-0.10.4-1.1.el6sat.noarch

How reproducible:
100%

Steps to Reproduce:
1. @sat6 obtain wrong build instruction:
# hammer import content-host --csv-file=/tmp/export/system-profiles.csv --export-directory=/root/content-hosts

2. @sat6 build the rpm:
# rpmbuild -ba --define "_topdir /root/content-hosts" /root/content-hosts/SPECS/system-profile-transition-*.spec

3. @sat5 built rpm requires advanced rpmlib capabilities:
# rpm -ivh /root/system-profile-transition-<fqdn>-1409658421-0.0.1-1.noarch.rpm
error: Failed dependencies:
	rpmlib(FileDigests) <= 4.6.0-1 is needed by system-profile-transition-<fqdn>-1410316694-0.0.1-1.noarch
	rpmlib(PayloadIsXz) <= 5.2-1 is needed by system-profile-transition-<fqdn>-1410316694-0.0.1-1.noarch


Actual results:
the rpm built on rhel6/7 cannot be installed on rhel5

Expected results:
the rpm built on rhel6/7 can be installed on rhel5
