package/eudev: add openrc init support

From: Carlos Santos <unixmania@gmail.com>

Add a udev-gentoo-scripts subpackage with the Gentoo scripts for openrc
and select it when BR2_INIT_OPENRC=y.

Why do you source it from the eudev package? You should treat it like
any other package; eudev will select it when it needs it.

We already have similar stuff, like the appropriate skeleton is
selected depending on the init system that is enabled. Or the
musl-compat-headers that is automatically selected by musl-based
toolchains...

What about being a bit more verbose:

    # Avoid installing the sysv S10udec script with openrc, as the
    # service is started by a unit from the udev-gentoo-scripts package.

Ditto: no need to source it from eudev.

Move it with (almost) all the other packages, into package/udev-gentoo-scripts/
(i.e. not in a subdir of eudev).

Don't we also need to handle the 'udev' unit too?
