combo-layer: fix file_exclude for empty commits

The code detecting empty patches after removing files with
file_exclude failed for commits which were already empty before (like
the initial commit in some repos): such patches are completely empty
files, without a From line.

Detect that case and just let the normal empty patch detection deal
with it.
