package/sane-backends: update the patches to be applied with fuzz 0

Commit 8f88a64 ("support/scripts/apply-patches.sh: set the maximum
fuzz factor to 0") reduced the fuzz factor.

Due to this change, sane-backends fails to build with output:

    Applying 0001-sane_backend-add-missing-config.h.patch using patch:
    patching file include/sane/sanei_backend.h
    Hunk #1 FAILED at 8.
    1 out of 1 hunk FAILED -- saving rejects to file include/sane/sanei_backend.h.rej

This commit refreshes the package patch on the current package version.
