fbcode_builder: getdeps: add NopBuilder

Browse Source 
Summary:
this could do with a better name; the NopBuilder doesn't actually
build anything, but instead copies some files to the destination location.

This is used together with eg: cmake to install pre-built binaries downloaded
from a tarball.
