Update AdjustIoPostprocessBuildPlayer.cs

[skjalgsm]

Fixed a bug where the PostProcessor would just open the Perl script on the build machine (mac OSX) instead of running the script.

@skjalgsm, I'd rather use /usr/bin/env perl PostbuildAdjustIoScript to execute the post-build script. Otherwise it would rely on having perl in $PATH. Also I'm wondering why it opens an executable script with a proper hashbang section instead of executing it? Cannot reproduce it locally (OSX).

I am not a competent OSX user, so I have no idea either. Both Perl and Python are installed on our build machine (OSX). Not sure if it was there by default or not, and not sure if it installs itself into $PATH by default or not either.

But I thought it was worth noting that this fixed our issue :)
