[PATCH v3 04/12] binman: Move 'external' support into base class

[Simon Glass]

At present we have an Entry_blob_ext which implement a blob which holds an
external binary. We need to support other entry types that hold external
binaries, e.g. Entry_blob_named_by_arg. Move the support into the base
Entry class to allow this.
