makefile: use LUA_PKGCONFIG to set Lua implementation

This breaks compat with the previous LUA_IMPLEMENTATION but gives more
flexibility in that user can specify the pkg-config package name
directly.

And if you'd like to specify a Lua implementation, you may use:
$ make LUA_IMPLEMENTATION=JIT
$ make LUA_PKGCONFIG=lua5.1
for using the LuaJIT project. Or:
$ make LUA_IMPLEMENTATION=VANILLA
for the mainline Lua project. If you specify neither implementation, it will
be auto-detected, preferring LuaJIT if both are present.
If this is not specified, the Lua implementation will be auto-detected,
preferring LuaJIT if many are present. Acceptable values are generally "lua",
"luajit", "lua5.1", and "lua5.2".
