[PATCH v4 2/2] regression_tests: add offloads alias

[Kamil Jerabek]

This commit adds offloads alias to all phase1 and phase2 tasks in our
regression_tests directory. If the alias is used, offloads and offload_settings
defined in task are overwriten.

Signed-off-by: Kamil Jerabek <kjerabek(a)redhat.com&gt;

---
v2: * static offloads definition merged into one if else statement with offloads
      alias
    * changed variables names
