scripts/combo-layer: fix overzealous regex in default hook script

combo-layer's hook scripts are intended to modify patches as they pass
through; the default one adds a prefix with the component name and
a line with the component repo revision before the Signed-off-by;
however the script was also unintentionally modifying the contents of
patches *within* the patches passing through it, which resulted in
unexpected failures when the combo-layer script attempted to use
"git am" to apply them.
