Subject: rockspec: re-add deprecated function type().

Removing this broke the behavior of some luarocks.build
plugins. LuaRocks does not have a stable public API,
but since this function was returned as part of the
function signature, we'll revert this as a deprecated
function, to be removed in LuaRocks 4.0.

Closes #1800.
