util/nvmutil: remove arc4random for portability

just use /dev/urandom and fall back to /dev/random

this is what i was doing for years. this combined
with other changes, and the new prw() function
for i/o, means portability should be pretty high
now. i will actually start testing nvmutil on old
bsd systems from the 90s later.
