lib/oe/lsb: Make sure the distro ID is always lowercased

In commit 8689e561 (lib/oe/lsb: attempt to ensure consistent distro id
regardless of source), the distro ID returned by
oe.lsb.distro_identifier() was lowercased, but only if a release
version is also present.

This changes the code to always lowercase the distro ID, including the
default distro ID "unknown", which is used if no other ID can be
identified.
