test/io/wait/test_io_wait_uncommon.rb: relax /dev/random check

Browse source 
Too many machines lack entropy to have a usable /dev/random.  I
had similar problems on my system until I started using
haveged(8), but we can't require that for CI.

cf. https://rubyci.org/logs/rubyci.s3.amazonaws.com/debian/ruby-trunk/log/20180825T213003Z.fail.html.gz
