Fix for build break
Simple fix for build break. Requesting review from Igor as it was his patch that broke non-mmap builds.
What systems don't have mmap? I'm curious!
OS/2 is one, according to http://hg.mozilla.org/mozilla-central/annotate/e6b318aca788/js/src/xpconnect/loader/mozJSComponentLoader.cpp#l104 it's the only one.
