Define the timeout to 24h for Ginkgo V2

Default timeout setting has been reduced from `24h` down to `1h` in
Ginkgo V2, but for some long running test this is too short.

How long to abort the test was controlled by the the linux command `timeout`
in V1. e.g. `'timeout -k 30s 150m ...`, and is configured in the file
like `sig-network-misc.yaml`.

Set the timeout manually for Ginkgo V2 to avoid the early aborting.
