Matthew Bauer 54210573c1 stdenv/native: provide patchelf on linux
This provides consistency with the pure stdenv, which provides
patchelf this way. Native stdenv can always just manually install
patchelf on their system, but like xz, it’s unlikely to be provided in
/usr/bin/. In addition, it’s not even in the RHEL7 repos.
