[Buildroot] [PATCH 03/25] luarocks-package: use $(HOST_PKG_VERSION) instead of $(PKG_VERSION)

[Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>]

The inner-luarocks-package macro was using $(3)_VERSION as the package
version, i.e. the version of the target package, even when it's the
host package. We should instead use $(2)_VERSION, i.e. the host package
version, like is done in inner-generic-package.

Since luarocks-package doesn't even support a host version, it doens't
make a whole lot of difference, but let's keep things consistent.
