ci: fix for codespell 2.2

Recently released codespell 2.2 adds some more false positives,
such as:

	./Makefile:78: ro ==> to, row, rob, rod, roe, rot
	./Makefile:88: ro ==> to, row, rob, rod, roe, rot
	./notify_socket.go:51: ro ==> to, row, rob, rod, roe, rot
	./LICENSE:128: complies ==> compiles
	./go.sum:59: BU ==> BY
	./types/features/features.go:17: ro ==> to, row, rob, rod, roe, rot
	./libcontainer/rootfs_linux.go:52: ro ==> to, row, rob, rod, roe, rot
	./libcontainer/rootfs_linux.go:166: ro ==> to, row, rob, rod, roe, rot
	....
	./tests/integration/cgroup_delegation.bats:38: inh ==> in
	...

To fix:
 - exclude go.sum;
 - add ro and complies to the list of ignored words;
 - s/inh/inherit in cgroup_delegation.bats.
