install_plt_redirect() should ultimately be replaced with GOT poisoning when redirecting PLT calls to patched version of a function

GOT poisoning on PIE binaries from Shiva is tricky, if Shiva updates the GOT then it will be overwritten by RTLD afterwards due to strict linking. The solution we used in the past (And should be employed now). Is for Shiva to update the appropriate GOT entry, followed by removing the JUMPSLOT relocation entry for that particular GOT entry.
