updatebase.GRMLBASE: execute fcopy with -i flag to ignore non-matching files

Otherwise when building testing/unstable we get:

| fcopy: no matching file for any class for etc/apt/preferences.d/wheezy-backports defined.

and fcopy fails to execute:

| updatebase.GRMLBASE  FAILED with exit code 1.

and causing the following '$ROOTCMD apt-key add /etc/apt/grml.key
to never get executed then.
