[ACT][PATCH] UBUNTU: SAUCE: ubuntu_lttng_smoke_test: create swap not only for Azure

[Po-Hsu Lin]

BugLink: https://bugs.launchpad.net/bugs/1803118
         https://bugs.launchpad.net/bugs/1926962

The OOM issue while trying to build this DKMS module on smaller
instances can be found on other clouds (AWS / GCP) as well.
Apart from that we will run generic kernel on these clouds, therefore
using swap file just for Azure cloud kernel is not enough.

Remove the if statement so that other variants can benefit from this.
