[libFuzzer] Fix __sanitizer_print_memory_profile return type in ExtFunctions.def

[Dor1s]

Summary

Looks like a typo, as that function actually returns void and is used
as such in libFuzzer code as well.

[Dor1s]

TBR as it seems to be a trivial fix. Tests do not break locally. Will revert if anything goes wrong :)
