QSysInfo: expand Linux distribution detection to /etc/lsb-release

Some older (or weird) Linux distributions don't have /etc/os-release, so
let's try to read /etc/lsb-release instead. If we find a file called
/etc/<distronamelowercase>-release and it's bigger than the pretty name
we read from /etc/lsb-release, use that.

Because the order of the keys changes between the two *-release files,
we can't do a sorted search anymore.
