If an ebuild uses EGO_SUM and needs to define a custom src_unpack phase,
these functions will make that easier.
go-module_setup_proxy is used to create a local file proxy of the
dependencies listed in EGO_SUM and go-module_filter_proxy is used to
create a new ${A} with the EGO_SUM_SRC_URI values removed.
