xzless: Fix less(1) version detection when it contains a dot.

Sometimes the version number from "less -V" contains a dot,
sometimes not. xzless failed detect the version number when
it does contain a dot. This fixes it.

Thanks to nick87720z for reporting this. Apparently it had been
reported here <https://bugs.gentoo.org/489362> in 2013.
