Fix trapa value for _syscall6() to conform with new sh syscall ABI.
The old sh system call interface used 0x00 - 0x0f for the trapa value
(number of arguments), whereas the new ABI uses the 0x10 - 0x1f range.
For some reason we were using an off-by-1 trapa immediate which ended up
trashing r1 in the _syscall6() case, so we fix it up..
