fix(quickget): skip unsupported architectures for all operations

- Remove the OPERATION == "test" guard so is_arch_supported() is
evaluated
  unconditionally
- Apply the unconditional arch check in test_all() for editions loop,
  ubuntu-server, ubuntu desktop (ubuntu*), and the default case
- Skip generating URLs / running further logic when an OS is not
available
  for the requested ARCH
IMPACT: quickget will no longer attempt to generate or test downloads
for
architectures that the distro does not support, preventing incorrect URL
generation and false-positive test attempts.
