openram devices extracted as special do not match source spice netlist.

[d-m-bailey]

Changes in commit 5cb6c4396a1e58cdc3ef95c4f2e4aeb84a434dc8 on Feb. 12, 2024 to extract devices with un-binned parameters as special models cause mismatch in openram macros because the source netlists have normal models.

For the sky130_sram_1kbyte_1rw1r_32x256_8 macro
