OS X patch for run_erl.c

[Sean Hinde]

Hi,

The following patch to run_erl.c is required for Erlang to run in 
embedded mode under OS X. Without this patch run_erl fails to create 
the pipe in /tmp

Hopefully this will make it into R9C-1, but in the meantime here it is 
in case anyone else has encountered the problem and needs a fix now.

Regs,
Sean
