tests: Optimize integration test on AArch64

Browse Source 
AArch64 tests were divided into 2 steps:
- Build and test with 'acpi' feature
- Build and test without 'acpi'

This can be optimized. We need only to build and test once with default
features ('acpi' is enabled).

On AArch64, ACPI only works with UEFI. If UEFI is not available, guest
kernel fall back to use FDT. Most AArch64 test cases boot from direct
kernel, the guest will keep using FDT even if ACPI is enabled. So
nothing is broken.
