Moved CDL file from SIGNOFF_ROOT to WORK_ROOT.

This means that only the $TOP_LAYOUT.gds.spice.gz is saved in SIGNOFF_ROOT,
and that the CDL file will be recreated when run_cvc or run_oeb_check is run.

Since work directories are deleted if there are no errors,
use separate work directories for LVS and OEB.
