Fix sepgsql regression tests (9.2-only patch). The regression tests for sepgsql were broken by changes in the base distro as-shipped policies. Specifically, definition of unconfined_t in the system default policy was changed to bypass multi-category rules, which the regression test depended on. Fix that by defining a custom privileged domain (sepgsql_regtest_superuser_t) and using it instead of system's unconfined_t domain. The new sepgsql_regtest_superuser_t domain performs almost like the current unconfined_t, but restricted by multi-category policy as the traditional unconfined_t was.
The custom policy module is a self defined domain, and so should not be affected by related future system policy changes. However, it still uses the unconfined_u:unconfined_r pair for selinux-user and role. Those definitions have not been changed for several years and seem less risky to rely on than the unconfined_t domain. Additionally, if we define custom user/role, they would need to be manually defined at the operating system level, adding more complexity to an already non-standard and complex regression test. Applies only to 9.2. Unlike the previous similar patch, commit 794e2558b, this also fixes a bug related to processing SELECT INTO statement. Because v9.2 didn't have ObjectAccessPostCreate to inform the context when a relation is newly created, sepgsql had an alternative method. However, related code in sepgsql_object_access() neglected to consider T_CreateTableAsStmt, thus no label was assigned on the new relation. This logic was removed and replaced starting in 9.3.
