perf tools: Allow specifying proc-map-timeout in config file

Browse Source 
The default timeout of 500ms for parsing /proc/<pid>/maps files is too
short for profiling many of our services.

This can be overridden by passing --proc-map-timeout to the relevant
command but it'd be nice to globally increase our default value.

This patch permits setting a different default with the
core.proc-map-timeout config file parameter.
