BPF tests fail sometimes with "bytes != total_bytes" errors:

 # test_default:PASS:sched_init:default 0 nsec
 # send_data:PASS:pthread_create 0 nsec
 # send_data:FAIL:recv 936000 != 10485760 nr_recv:-1 errno:11
 # default: 3041 ms
 # server:FAIL:send 7579500 != 10485760 nr_sent:-1 errno:11
 # send_data:FAIL:pthread_join thread_ret:-11test_default:PASS:has_bytes_sent addr_1 0 nsec
 # test_default:PASS:has_bytes_sent addr_2 0 nsec
 # close_netns:PASS:setns 0 nsec

"bytes != total_bytes" is not a fatal error for BPF test, just print out
the error info and skip it.

This patch makes BPF tests stable.
