[PATCH] tests: disassemble-asm.sh: generate AML in readable format

["Michael S. Tsirkin" <mst@redhat.com>]

On systems where the IASL tool exists, we can convert
extected ACPI tables to ASL format, which is useful
for debugging and documentation purposes.
This script does this for all ACPI tables under tests/data/acpi/.
