config: regenerate *_shipped sources

The pregenerated `zconf.hash.c` and `zconf.lex.c` files have not been
kept in sync with their respective `*.y` and `*.l` sources in the past
causing our kconfig implementation to not recognize important kconfig
grammer elements such as relational `<`, `<=`, `>` and `>=` operators.

Fixes: 2d7e602381f3 ("scripts/config: sync with latest linux upstream")
