[jumbo][extensions] Give two kPrefsName unique names

In jumbo builds many cc files compile in the same translation unit
which also means that they share the same anonymous namespace. That
means that constant names need to be unique in the whole build
target even if they are in anonymous namespaces.

A service worker extension just introduced a second kPrefsName into
extensions/browser which broke some (but not all) jumbo build
configurations. This patch renames them both to prevent
confusion (from compiler or human).
