Fix globbing to find remote python

From: truty@google.com

There is a problem we observe with chromeos that a logfile.monitor error
occurs in our jobs.  The problem is illustrated below.  When
list_remote_pythons() is invoked in logfile_monitor.py, it mistakenly grabs
/usr/bin/python-config-2.6 as it's interpreter.  This patch seems a tiny bit
more careful in identifying the proper interpreter.
