lua: smarter/more correct patching

In order to have the 'reset' LUA_PATH (aka `;;`) work, and for purity
reasons(removing /usr paths) we(I) decided to patch the lua interpreters default LUA_PATH.
Turns out the interpreters have different defaults and the patch was too
coarse.
There is smarter patching that can be done via LUA_ROOT.

Also luajit doesn't need patching at all since LUA_ROOT is set via the
build system.
