Support vCont s and S actions with software single step
GDBserver with software single step should be able to claim supporting
vCont s and S actions, so that GDB knows the remote target can do
single step. It doesn't matter to GDB that the single step in the
remote target is done via hardware or software.
gdb/gdbserver:

* server.c (handle_v_requests): Support s and S actions
if target_supports_software_single_step return true.
