sysutils/fsearch: unbreak fetching of the upstream patches

Once again, GitHub had changed the generated metadata slightly,
in the following lines (all of them):

  -index ca5a270..9972426 100644
  +index ca5a2703..99724260 100644

While here, add couple of missing Oxford commas, drop the plus
from the GTK name (since February 2019), and reword the port
description a bit.
