038-cfg: disable BSCAN PDRC-2 DRC (Vivado 2020.1) 

Failed bitgen with 'ERROR: [DRC PDRC-2] BSCAN_JtagChain: Unsupported
programming for BSCAN site BSCAN_X0Y0 and JTAG_CHAIN attribute value
3.' Same DRC already disabled in fuzzers/005-tilegrid/cfg/generate.tcl
for the same reason — Vivado 2020.1 tightened this check vs 2017.2.
Add the matching disable here.
