tests/functional: Adapt arches to reverse_debugging w/o Avocado

Browse source 
reverse_debugging no longer depends on Avocado, so remove the import
checks for Avocado, the per-arch endianness tweaks, and the per-arch
register settings. All of these are now handled in the ReverseDebugging
class, automatically.
