perf config: Add '--system' and '--user' options to select which config file is used
The '--system' option means $(sysconfdir)/perfconfig and '--user' means
$HOME/.perfconfig. If none is used, both system and user config file are
read. E.g.:
# perf config [<file-option>] [options]
With an specific config file:
# perf config --user | --system
or both user and system config file:
# perf config
