[erlang-patches] Fix DTrace build on Illumos

Hello Ryan,

I just noticed that you removed the "2> /dev/null" for the 2STEP_TEST in 
erts/configure.in. Was there a reason for doing that? As it is now when 
the test fails on osx in prints the output of the dtrace command to the 
shell which is not really what you want.
