Update node-7.1.0.sh added additional 'sed'

Thanks for your build script. It was one of the few working ones I found. It compiled Node `7.10.1` (using ndk r15 latest) successfully.
It does not compile Node as shared library unfortunately.

One addition to the script that was necessary however, was undefining `HAVE_GETSERVBYPORT_R`
