Subject: [PATCH 03/16] perf script: Fix vanished idle symbols

Patch "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.
