Correctly detect more Linux distributions

I don't think there's a way we can track all of the variations here, but
this supports any distribution that supports the lsb-release standard and
adds extra detection to correctly decode the PCLinuxOS version as they
neither implement /etc/os-release nor completely implement
/etc/lsb-release
