Remove Hardcoded Paths

Created by: rosethompson

There are still several locations in the scripts with hardcoded paths specific to either HMC or OSU servers. I'm going to use this issue to track these locations until they are all found.

Synthesis:

synthDC/.synopsys_dc.setup
    set pdk /proj/models/tsmc28/libraries/28nmtsmc/tcbn28hpcplusbwp30p140_190a/                                                                                                                                   
    set osupdk /import/yukari1/pdk/TSMC/28/CMOS/HPC+/stclib/9-track/tcbn28hpcplusbwp30p140-set/

    set memory /home/jstine/WallyMem/rv64gc/                                                                                                                                                                      
    set osumemory /import/yukari1/pdk/TSMC/WallyMem/rv64gc/
