risu: move optional args to each architecture

The key variables here are: *arch_long_opts and *arch_extra_help. If
they are not NULL then we concatenate the extra options to appropriate
structure to enable the support. Adding architecture short options is
not supported.

This also includes moving the ARM specific test_fp_exc/test-fp-exc
into ARM specific code.
