cmake/lua: fix lua autodetection

Hi,

tb@ signaled some build problems with geo/osrm-backend when lua5.4 was junked
during the build, whereas osrm-backend is expected to use lua5.3.

After looking a bit to the build, osrm-backend was using include files from
lua5.3 and library from lua5.4: the configure stage using LUA_INCLUDE_DIR passed
in CONFIGURE_ARGS and autodetecting the library (and picking 5.4).

Passing both LUA_INCLUDE_DIR and LUA_LIBRARY in CONFIGURE_ARGS fix it.

I built a set of ~50 ports on amd64 (based on ports using both devel/cmake and
lang/lua MODULES) to ensure it creates no problem at build time.

Comments or OK ?
