[Buildroot] [PATCH v2 09/14] package/systemd: option to delete all catalog files

[Jérémy ROSEN]

Hey Norbert

this is similar to the way hwdb source files are handled and,
if my understanding is correct, the general buildroot
philosophy is that that sort of files are not needed on the
target at all, since buildroot does not support on-target
updates. So i don't think an option is required, just
remove the files. (I'm a bit fuzzy on the buildroot philosophy,
but that's my understanding. If a real dev disagree, follow their
advice...)
