[PATCH] opjitconv change to avoid bogus error message in log

[Maynard J. <may...@us...>]

This patch was needed to correspond with the previous change I made
allowing oprofile to be installed without the new 'oprofile' user
account existing.  Profiling non-JIT code without the new user account
on the system was resulting in bogus messages in oprofiled.log because
opjitconv (which is exec'ed by the daemon) was trying to change the
ownership of a temp directory before it even knew if there were any JIT
dump files to process.  So this patch moves the check for the existence
of JIT dump files ahead of the change ownership code.
