[U-Boot] [PATCH 2/3] scripts/Makefile.lib: generalize building built in EFI app

Tue Sep 5 01:19:38 UTC 2017
Replace all occurences of helloworld by generalized forms.
This allows us to build additional EFI applications that are
included into the U-Boot binary without loading
scripts/Makefile.lib with specific filenames.
