fix sendfile syscall to use 64-bit off_t
somehow the remapping of this syscall to the 64-bit version was overlooked. the issue was found, and patch provided, by Stefan Kristiansson. presumably the reason this bug was not caught earlier is that the syscall takes a pointer to off_t rather than a value, so on little-endian systems, everything appears to work as long as the offset value fits in the low 31 bits. on big-endian systems, though, sendfile was presumably completely non-functional.
