luajit: LuaJIT has a "rolling release" where we should follow git HEAD

Maintainer: @milani
Environment: build system

Description: LuaJIT has a "rolling release" where we should follow git HEAD[1]. I believe that the currently tagged version is tracking code from 2017. Can we update our package to track HEAD? I made an attempt to modify it based off lang/luajit2/Makefile but the patches need a refresh.

Inspect lang/luajit/Makefile and compare it with lang/luajit2/Makefile first. Refresh the patches for the git-based LuaJIT source, then build the package to verify it follows the intended HEAD snapshot and the package build completes.
