Update README and pulpcore.te

Changed building and installing steps in README:
- Pulp_port module has to be installed first, except for Fedora 31 and Fedora Rawhide in which pulp_port type is included in the base SELinux policy.
- The SELinux policy for Pulp was this way successfully installed on Fedora 30, Fedora 31, Fedora Rawhide, RHEL 7.5, RHEL 7.8, RHEL 8.0, RHEL 8.1 and RHEL 8.2 Beta.

Update pulpcore.te file:
- miscfiles_read_certs() replaced by miscfiles_read_generic_certs(), because miscfiles_read_certs() has been deprecated.

Fixed: https://pulp.plan.io/issues/6048

 communicate on with the network correctly.
