[OE-core] [PATCHv3] wic: fix images build in parallel

[Maxim Uvarov]

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.
