Ticket #37 (new defect)

Description

Normal scriptlets on SELinux enabled system get executed through rpm_execcon() libselinux call, but Lua scriptlets execute in rpm itself, which might not have the same permissions as scriptlets.

For example RhBug:483089 - groupadd is permitted for rpm_script_t but not for rpm_exec_t. One possibility could be SELinux-aware version of os.execute() such as rpm.execute() in the local Lua extensions which uses exec() or rpm_execcon() as appropriate.
