wire: locale-independent patch order for EXPERIMENTAL_FEATURES patches

Also, remove fuzz caused by varint->bigsize change.

For some reason my build machine sorts patches into another order, and fails
to patch:

	patching file wire/gen_onion_wire_csv.104951
	Hunk #1 succeeded at 52 with fuzz 1 (offset -19 lines).
	patching file wire/gen_onion_wire_csv.104951
	Hunk #1 FAILED at 8.
	1 out of 1 hunk FAILED -- saving rejects to file wire/gen_onion_wire_csv.104951.rej
	make: *** [wire/Makefile:60: wire/gen_onion_wire_csv] Error 1
