win64: fix lookup of RtlAddFunctionTable() helper for v8

This helper function moved from chrome.exe to chrome_elf. The failure to
look up is unfortunately silent because the same code is used in test
binaries. As a result, RtlAddFunctionTable() wasn't called, so any
crashes with v8 jit on the stack on Win x64 caused program termination
without giving our crash handler a chance to catch it.
