Fix contrib/sepgsql test policy to work with latest SELinux releases.

Browse Source 
As of Fedora 30, it seems that the system-provided macros for setting
up user privileges in SELinux policies don't grant the ability to read
/etc/passwd, as they formerly did.  This restriction breaks psql
(which tries to use getpwuid() to obtain the user name it's running
under) and thereby the contrib/sepgsql regression test.  Add explicit
specifications that we need the right to read /etc/passwd.

Mike Palmiotto, per a report from me.  Back-patch to all supported
branches.
