MFC r239962:

Fix a twelve year old bug in readelf: when process_dynamic_segment()
encounters a DT_RUNPATH entry, the global dynamic_info[] array is
overrun, causing some other global variable to be overwritten.

In my testcase, this was the section_headers variable, leading to
segfaults or jemalloc assertions when it was freed later on.

Thanks to Koop Mast for providing samples of a few "bad" .so files.
