[Buildroot] [PATCH 1/1] luarocks: fix target-finalize hook processing

[Danomi Manchego]

The LUAROCKS_TARGET_FINALIZE_HOOKS is not running, so detritus
it being left in /usr/lib/luarocks.  This is because luarocks is
built by being a dependency in the luarocks package infrastructure,
not by being selected by kconfig symbol. This means that the
$(PKG)_KCONFIG_VAR in pkg-generic.mk is not met, and
(HOST_)LUAROCKS_TARGET_FINALIZE_HOOKS is not added to the global
TARGET_FINALIZE_HOOKS.

This mod fixes this issue by adding the host-luarocks hook directly
to TARGET_FINALIZE_HOOKS when either lua or luajit is enabled.
