selftests/bpf: Move get_time_ns to testing_helpers.h
We'd like to have single copy of get_time_ns used b bench and test_progs,
but we can't just include bench.h, because of conflicting 'struct env'
objects.
Moving get_time_ns to testing_helpers.h which is being included by both
bench and test_progs objects.
