EVL: hectic test fails when to many CPUs are available

[Hannes Diethelm <hannes.diethelm@gmail.com>]

Hello

This is the reason for the patch for evl-test. I guess a beginners mistake / edge case but
if you want to look into it:

If I don't set evl.oobcpus in my VM or just use to many OOB CPUs, the hectic test crashes and
never exits. I have to use kill -9 to stop it.

evl_attach(): Resource temporarily unavailable: This is probably not handled correctly.

evl.oobcpus=0-15 -> Freeze
evl.oobcpus=1-15 -> Freeze
evl.oobcpus=2-15 -> Ok

/usr/libexec/evl/tests/hectic -T 5
