opensp: Fix hard path in native nsgmls.

This relocation issues caused following bug and introduce one partial fix bb024d:
[YOCTO #1440]

But the environment val hacking is not working all the time, as nsgmsl may
append wrong path in some case. This fix use search directory "-D" as solution.
And more important, change the iputils' way to make doc: Use the sysid in
current directory instead of parent directory, as "../" is also appended to the
search directory then lead searching failure.
