[Libguestfs] [PATCH 2/5] inspect: detect Gentoo from os-release

[Pino Toscano]

Add "gentoo" as recognized ID in /etc/os-release, and consider it as
rolling distribution (so without VERSION_ID in os-release).

This avoids using a not-useful version read from /etc/gentoo-release,
e.g. "Gentoo Base System release 2.6".
