UNIX - Get Proxy Filename. Get the proxy cert filename based on the following search order:

	1.		X509_USER_PROXY environment variable - This environment variable is set by the at run time for the specific application. If the proxy_file_type variable is set to GLOBUS_PROXY_OUTPUT (a proxy filename for writing is requested), and the X509_USER_PROXY is set, this will be the resulting value of the user_proxy filename string passed in. If the proxy_file_type is set to GLOBUS_PROXY_INPUT and X509_USER_PROXY is set, but the file it points to does not exist, or has some other readability issues, the function will continue checking using the other methods available.
