grant permission for rpm to write to audit log 

Messages like this are added to the audit log when an rpm is installed:
type=SOFTWARE_UPDATE msg=audit(1560913896.581:244): pid=1265 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:rpm_t:s0 msg='sw="ntpdate-4.2.6p5-25.el7_3.2.x86_64" sw_type=rpm key_enforce=0 gpg_res=0 root_dir="/" comm="rpm" exe="/usr/bin/rpm" hostname=? addr=?  terminal=? res=success'

These are the denials that I'm seeing:
type=AVC msg=audit(1560913896.581:243): avc:  denied  { audit_write } for  pid=1265 comm="rpm" capability=29 scontext=system_u:system_r:rpm_t:s0 tcontext=system_u:system_r:rpm_t:s0 tclass=capability permissive=1

type=AVC msg=audit(1561298132.447:243): avc:  denied  { read } for pid=1266 comm="rpm" scontext=system_u:system_r:rpm_t:s0 tcontext=system_u:system_r:rpm_t:s0 tclass=netlink_audit_socket permissive=1

v2 - Use interface rather than adding permissions here - this change may
confuse subsequent patches in this set, if so let me know and I will
submit a pull request on github.
