perf config: Mark where are config items from (user or system)
To write config items to a particular config file, we should know where
is each config section and item from.
Current setting functionality of perf-config use autogenerating way by
overwriting collected config items to a config file.
For example, when collecting config items from user and system config
files (i.e. ~/.perfconfig and $(sysconf)/perfconfig), perf_config_set
can contain both user and system config items. So we should know where
each value is from to avoid merging user and system config items on user
config file.
