enable hw builds of md5

I recently had web-md5 fail to build as it doesn't pass timing. This PR will run automated tests against md5 for new compiler releases.

Build ID: 127dd631-2755-4eaa-9ba6-ed8a2c5bed42

Logs from 4th step onwards:

Finished 4th of 5 tasks (FPGA routing). Elapsed time: 01h 50m 46s.
