perf annotate: Pass hist_entry to annotate functions

It's a prepartion to support code annotation and data type
annotation at the same time.  Data type annotation needs more
information in the hist_entry so it needs to be passed deeper.

Also rename a function with the same name in the builtin-annotate.c
to hist_entry__stdio_annotate since it matches better to the command
line option.  And change the condition inside to be simpler.
