Do not setup machine exception vector.

Sounds strange, but both RocketCore and lowRISC do not operate
if we set it.

All the known implementations (Spike, QEMU, RocketCore, lowRISC) uses
default machine trap vector address and operates fine with this.

Original Berkeley Boot Loader (bbl) does not set this as well.
