Ani Sinha 5a37392411 acpi/tests/avocado/bits: add SPDX license identifiers for bios bits tests 
Added the SPDX license identifiers for biosbits tests.
Also added a comment on each of the test scripts to indicate that they run
from within the biosbits environment and hence are not subjected to the regular
maintenance activities for QEMU and is excluded from the dependency management
challenges in the host testing environment.
