disallow setid binaries with $ORIGIN in PT_INTERP
Currently $ORIGIN is honored in a PT_INTERP section regardless of whether the binary is setid or not. If a binary were constructed and setid in this way, it would allow someone else to play games with the interpreter. While this is an extremely rare combination, it's worth clamping it off at the bit.
