Mac OS X: Fix getProcessName() to avoid assertion failure in truncate

Apparently _NSGetExecutablePath doesn't actually set the len field in
the case of successfully copying a value to buf. In this case, the
value in buf is properly terminated, so we can just use strlen to find
a legal value to use when calling truncate.
