Fortuna: Add failpoints to simulate initial seeding conditions

Set debug.fail_point.random_fortuna_pre_read=return(1) and
debug.fail_point.random_fortuna_seeded=return(1) to return to unseeded
status (sort of).  See the Differential URL for more detail.

The goal is to reproduce e.g. Lev's recent CURRENT report[1] about failing
newfs arc4random(3) usage (fixed in r338542).

No functional change when failpoints are not set.
