Subject: build: automate clean-up of shipped scanner and parser

* Makefile (shipped): Copy the shipped materials unconditionally,
rather than checking if they are different. If a patch exists
for a shipped file, then apply it.

* lex.yy.c.shipped, y.tab.c.shipped: Updated.

* lex.yy.c.patch, y.tab.c.patch: New files.
