selftests: bonding: reduce garp_test/arp_validate test time

Browse Source 
The purpose of grat_arp is testing commit 9949e2efb5 ("bonding: fix
send_peer_notif overflow"). As the send_peer_notif was defined to u8,
to overflow it, we need to

send_peer_notif = num_peer_notif * peer_notif_delay = num_grat_arp * peer_notify_delay / miimon > 255
  (kernel)           (kernel parameter)                   (user parameter)

e.g. 30 (num_grat_arp) * 1000 (peer_notify_delay) / 100 (miimon) > 255.

Which need 30s to complete sending garp messages. To save the testing time,
the only way is reduce the miimon number. Something like
30 (num_grat_arp) * 100 (peer_notify_delay) / 10 (miimon) > 255.

To save more time, the 50 num_grat_arp testing could be removed.

The arp_validate_test also need to check the mii_status, which sleep
too long. Use slowwait to save some time.

For other connection checkings, make sure active slave changed first.
