Remove use of deprecated infra_paths module.

We are finally free of buildbot!

For reference, infra_paths was mostly a wrapper for these config
tweaks:
https://source.chromium.org/chromium/chromium/tools/depot_tools/+/master:recipes/recipe_modules/infra_paths/path_config.py

The infra_paths module added things like 'api.path['builder_cache']'
as base paths, but only under some environmental contexts (like
buildbot). It used to do quite a bit for buildbot and kitchen-on-buildbot
but does almost nothing for LUCI.

All LUCI builds use the 'generic' path configuration which only made
the following substitutions:

   api.path['builder_cache'] == api.path['cache'].join('builder')
   api.path['git_cache'] == api.path['cache'].join('git')
   api.path['goma_cache'] == api.path['cache'].join('goma')

Now, instead of relying on these base paths being set indirectly
via depot_tools, we prefer to just directly use the 'cache' base
path.
