wic: fix images build in parallel

OE wic plugins create temporary file with the index of the line
tmp file name. This causes race in case several builds run in time.
If source_params['file'] is an absolute path, the cr_workdir prefix
is not applied by os.path.join(). So instead it writes to a ".1"
file next to the original image - this is outside the WORKDIR
and at risk of collision.
