[test] fix test_mle_msg_key_seq_jump (#7952)

Browse Source 
This commit updates `test_mle_msg_key_seq_jump` to increase the wait
time after key index change for MLE advertisement transmissions. The
MLE advertisement uses trickle timer with max interval of 32 seconds.
Based on this the max interval between two consecutive advertisement
transmissions can be 1.5 times the trickle timer max interval or 48
seconds. The test uses 52 sec as wait time which includes a 4 sec
additional guard time to account for any action and/or message
exchanges after rx of an advertisement. This change should help
address the occasional failures of this test.
