Commit 608c34de0b3d ("perf symbols: Mark if a symbol is idle in the
library") causes idle symbols to vanish from perf script output. That is
because print functions suppress symbols marked as 'idle'.

However, suppression of 'idle' functions is only used by 'perf top' and
'perf top' does not use the print functions.  Consequently that
functionality can simply be removed from the print functions.

Since this is the only use thus far, and this mechanism is in place for
a long time. To clarify why symbols should be skipped or treated
differently, name it for the only use it has.

They still use functions that would drag more stuff to the python
binding, where these fprintf methods are not used, so separate it.
