[Buildroot] [git commit branch/2017.08.x] ejabberd: Replace $(HOST_DIR) to /usr in ERL path

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=88a9a611d2d7bf600ad2788489026cbed23db132
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.08.x

Previously, it was working by luck. Buildroot has fixed its definition
of HOST_DIR and pkg-autotools.mk uses the classical /usr prefix. So,
fix this sed expression to correctly replace $(HOST_DIR) by /usr in ERL
path.
