objtool/klp: Don't report uncorrelated functions as new
Clang LTO uses __UNIQUE_ID() to generate some uniquely named wrapper
functions, like initstubs. If they're uncorrelated, prevent them from
being reported as new functions and included unnecessarily.
Note that dont_correlate() already includes prefix functions, so prefix
functions are still being ignored here.
