[Buildroot] [PATCH] core/pkg-generic: host variants inherits target's override-srcdir

[Yann E. MORIN]

When a package has both a target and a host variants, and there is an
override-srcdir set for the target variant, the host variant should
inherit the target's override-srcdir, unless explicitly set, like we do
for all other target-variant properties.
