Add "digdelv" test to simulate DiG network unreachable error

Browse Source 
There are existing tests for simulating timeouts, read errors, and
refused connecion errors. Implement also "network unreachable"
simulation.

Use "fixed" string search mode `-F` for `grep` in more places where
it is appropriate to do so.
