perf machine: Add symbol filter to struct machine

Browse source 
The symbol filter needs to be applied machine-wide, so add it to struct
machine.

Currently tools pass the symbol filter as a parameter to various
map-related functions.  However a need to load a map can occur anywhere
in the code, at which point the filter is needed.
