HAProxy: Unknown keyword lua-load
After upgrading pfSense from 2.4.3_1 to 2.4.4 our haproxy didn't started anymore.
The error we got was `Unknown keyword "lua-load"`
After some investigation we noticed with `ldd haproxy` that the lua library was not loaded anymore and it seems haproxy for 2.4.4 is not compiled with lua option anymore.
As a workaround we switched now to haproxy-devel, where it seems lua is still loaded, but we are not sure how stable the haproxy-devel branch is.
Comparing the `Makefile` between 2.4.3_1 and 2.4.4 there were some changes, but I'm not that good with Makefiles to be sure.
In 2.4.4. the `LUA_MAKE_ARGS` are never added to the `MAKE_ARGS` like in 2.4.3_1.
