Use nextest for FPGA workflow.

This has two benefits:

 * nextest will archive all the binaries for us, and we don't have to
   manually decide which ones to call in the workflow (a new test binary
   will be automatically invoked).

 * nextest generates the junit.xml file which can be used to inform a
   future test dashboard.
