Add pre-built attribute to host module definition for fake snapshot.
The host-snapshot provides host tools via prebuilt modules.
Having 2 prebuilts of the same module in a source tree leads to a build
time error. Add new attribute when building the fake snapshot to
indicate that the host tool contains a prebuilt version.
When installing the host snapshot the user can opt not to include
modules that have a prebuilt version.
