[Buildroot] [PATCH v2 1/3] libffi: fix headers location for host-libffi

[yegorslists at googlemail.com <yegorslists@googlemail.com>]

From: Yegor Yefremov <yegorslists@googlemail.com>

There is a special hook for target-libffi, that moves headers
from /usr/lib/libffi-version/include to /usr/include. This patch
adds the same procedure for host-libffi.
