selftests: forwarding: tc_flower: Relax success criterion
The test checks that filters that match on source or destination MAC
were only hit once. A host can send more than one packet with a given
source or destination MAC, resulting in failures.
Fix by relaxing the success criterion and instead check that the filters
were not hit zero times. Using tc_check_at_least_x_packets() is also an
option, but it is not available in older kernels.
