[vim/vim] configure failed with latest LuaJIT (Issue #12896)

[依云]

Steps to reproduce

1. try to build with luajit version 2.1.1692616192
2. it failed with

checking --with-luajit... yes
checking for luajit... /usr/bin/luajit
checking LuaJIT version... LuaJIT 2.1.1692616192 -- Copyright (C) 2005-2023 Mike Pall. https://luajit.org/
checking Lua version of LuaJIT... 5.1
checking if lua.h can be found in /usr/include/luajit-LuaJIT 2.1.1692616192 -- Copyright (C) 2005-2023 Mike Pall. https://luajit.org/... checking if lua.h can be found in /usr/include... no
checking if lua.h can be found in /usr/include/lua5.1... no
checking if lua.h can be found in /usr/include/moonjit-2.3... no
configure: error: could not configure lua

This is because LuaJIT no longer has a - in its version:

$ luajit -v 2>&1 | sed 's/LuaJIT \([0-9.]*\)\.[0-9]\(-[a-z0-9]*\)* .*/\1/'
LuaJIT 2.1.1692616192 -- Copyright (C) 2005-2023 Mike Pall. https://luajit.org/

Expected behaviour

Success.

Version of Vim
