[Buildroot] [git commit branch/next] lua: ensure that host-lua does not depend on host-readline and host-ncurses

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=2ebbec054545df978655eda88af78f531ff25f17
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Commit ad6af5819f88bac9ca7f50e565c4fc68d3e408cc removed the
HOST_LUA_DEPENDENCIES assignement to the empty variable, so from that
commit, the dependencies of host-lua are automatically computed from
the dependencies of lua. Since lua can depend on readline and ncurses,
it means that host-lua can depend on host-readline and host-ncurses,
and the host-readline package does not exist in Buildroot. Since there
is no reason to build host-lua with readline/ncurses support, just
re-add the HOST_LUA_DEPENDENCIES variable.
