  [memprof] Use unknown_function error type for missing functions

Switch the error type when a function is not found in the memprof
profile to unknown_function. This gives compatibility with normal PGO
function matching, and also prevents issuing large numbers of additional
matching errors since pgo-warn-missing-function is off by default.
