machine: Use error handling when CPU type is checked

Functions that use an Error **errp parameter to return errors should
not also report them to the user, because reporting is the caller's
job. The principle is violated by machine_run_board_init() because
it calls error_report(), error_printf(), and exit(1) when the machine
doesn't support the requested CPU type.

Clean this up by using error_setg() and error_append_hint() instead.
No functional change, as the only caller passes &error_fatal.
