hack/tools: bump logtools to v0.8.0

[pohly]

What type of PR is this?

/kind cleanup

What this PR does / why we need it:

This adds support for marking functions and methods as "don't use in code which supports contextual logging".

Special notes for your reviewer:

I found that I had to do _output/local/bin/golangci-lint cache clean to get rid of some false positives after the update:

ERROR: test/e2e/network/endpointslice.go:993:5: SA5011(related information): this check suggests that the pointer can be nil (staticcheck)
ERROR: 	if targetRef == nil {
ERROR: 	   ^
ERROR: test/e2e/network/endpointslice.go:996:15: SA5011: possible nil pointer dereference (staticcheck)
ERROR: 	if targetRef.Kind != "Pod" {
ERROR: 	             ^

This stopped being reported (as it should be, because the first if calls framework.Failf and that doesn't proceed) after cleaning the cache. Somehow the new fact in logcheck interfered with with the fact from staticcheck.

Does this PR introduce a user-facing change?

NONE
