lseek() and truncate() on sparc really need sign extension

Browse source

ftruncate() doesn't - it's declared with size as unsigned long,
but truncate() and lseek() have that argument as signed long.
IOW, these two really need sign extension + branch to native
syscall; argument validation in sys_... does *not* suffice.
