lua: update 5.3.6 -> 5.4.3

Drop three backports and 0001-Allow-building-lua-without-readline-on-Linux.patch
(feature added upstream, adjust the recipe accordingly).

Adjust ar/ranlib flags for reproducibility on liblua.a.

License-Update: lines moved around, formatting

-Barriers cannot be active during sweep, even in generational mode.
-(Although gen. mode is not incremental, it can hit a barrier when
-deleting a thread and closing its upvalues.)  The colors of objects are
-being changed during sweep and, therefore, cannot be trusted.

-Subject: [PATCH] Fixed bug: invalid 'oldpc' when returning to a function
-
-The field 'L->oldpc' is not always updated when control returns to a
-function; an invalid value can seg. fault when computing 'changedline'.
-(One example is an error in a finalizer; control can return to
-'luaV_execute' without executing 'luaD_poscall'.) Instead of trying to
-fix all possible corner cases, it seems safer to be resilient to invalid
-values for 'oldpc'. Valid but wrong values at most cause an extra call
-to a line hook.
