kbuild: prevent make from deleting _shipped files
commit 7373f4f (kbuild: add implicit rules for parser generation)
created a implicit rule chain (%.c: %.c_shipped: %.y).
Make considers the _shipped files to be intermediate files which
causes them to be deleted if they didn't exist before make was run.
Mark the _shipped files PRECIOUS to prevent make from deleting them.
