limactl stop: extend the timeout for waiting for the hostAgent to stop

Currently, both the timeout for waiting for the hostAgent to stop in `limactl stop` and the timeout for `LimaQemuDriver.Stop()` calling `shutdownQEMU()` are set to 3 minutes.
https://github.com/lima-vm/lima/blob/6fa914519f9412519fee64619755aa4a9b3774f9/pkg/qemu/qemu_driver.go#L204
As a result, the `limactl stop` might time out before QEMU is forcibly terminated, leading to the error:
> level=fatal msg="did not receive an event with the \"exiting\" status"

With this change, `limactl stop` should be able to receive the `"status":{"exiting":true}` event output by the hostAgent after it has forcibly terminated QEMU, preventing `limactl stop` from resulting in an error.
