            kernel/selinux-testsuite: extend SCTP test coverage

Add another global IPv4 address by creating a dummy GRE interface in
order to activate two extra SCTP tests that require two unique global
IPv4 addresses.

Before (F32):
Files=61, Tests=832, 176 wallclock secs ( 0.59 usr  0.13 sys +  4.92 cusr  6.54 csys = 12.18 CPU)

After (F32):
Files=61, Tests=834, 182 wallclock secs ( 0.66 usr  0.11 sys +  6.28 cusr  7.68 csys = 14.73 CPU)
