ptp4l: add override flag in cfg_settings to apply cmdline options 

This patch adds a flag field for setting overflag flags so that command line
options override any value in the configuration file. This will be done by
ensuring the flags set whether the config parser accepts the values specified.
This patch also streamlines the handling for the slave only command line
option, as it no longer needs special treatment.
