[PATCH 1/2] initramfs: don't include filenames from the initramfs for make goals (dist)clean

[Alexander Holler <holler@ahsoftware.de>]

Various unusual filenames might break the make process when they are included
as dependencies (e.g. filenames with a colon).

This has the disadvantage that not even a make (dist)clean does work afterwards.
What makes the matter worse is that git clean -df doesn't remove such a possible
broken dependency list too.

Avoid that by not including this dependency list for make goals (dist)clean.
