Let runtime_loader ignore RT_RELRO program headers.

Browse Source 
* The new libstdc++.so contains program headers of type PT_RELRO (for
  making segments read-only after relocation). While the actual feature
  has not been implemented, the runtime_loader should now silently
  accept (and ignore) those program headers.
