* Problem: Path appended twice to VRT file path

Once before calling create_vrt_permanent, and a second time inside
create_vrt_permanent.

It ended up trying to create a file with a path like:

./output/fieldmosaic/./output/fieldmosaic/fullfield_mosaic.vrt

Solution: Pass the bare filename (no path) into create_vrt_permanent

P.S. I also noticed and removed a redundant conditional statement (both
branches were exactly the same)
