test: Bump L4LB timeout from 30min to 45min
test: Bump L4LB timeout from 30min to 45min

From time to time it takes longer to run the tests. After adding
timestamps to each cmd, I don't see any discrepancies. I.e., all cmds
execution time is reasonable.

There is no need to bump the v1.1{0,1} actions' timeout, as they don't
run NAT46x64 test suite which is timing out.
