wic: Make sure file exists before removing it
Bunch of os.remove calls were added to the partition.py lately.
They're causing wic to fail with OSError: [Errno 2] No such file or directory
if file doesn't exist.
Added check for file existence to all recently added calls of
os.remove. That should fix this regression.
