[infra] Remove depot_tools from infra manifest
We use our own versions of prebuilts like lucicfg and vpython rather
than using Chromium's depot_tools versions, and ~never need to make
depot_tools modifications, so it's not necessary to include depot_tools
in an infra checkout.
It's also confusing to include depot_tools results when running grep
from the root of an infra checkout, since the depot_tools repo contains
some recipes that can easily be mistaken for our own fuchsia recipes.
I assume the original reason for including depot_tools in the infra
checkout was to permit access to lucicfg and other executables, but I
can't say for sure because the CL that added the dependency doesn't
provide any motivation: http://fxrev.dev/302149
