Peter Zijlstra d15cb3dab1 x86/livepatch: Validate __fentry__ location ...

Currently livepatch assumes __fentry__ lives at func+0, which is most
likely untrue with IBT on. Instead make it use ftrace_location() by
default which both validates and finds the actual ip if there is any
in the same symbol.
