log: set ident to openlog

at syslog side, log message is identified by its properties like
programname, pid, etc.  brick/mount processes need to be identified
uniquely as they are different process of gluterfsd/glusterfs.  At
rsyslog side, log separated by programname/app-name with pid works but
bit hard to identify them in long run which process is for what
brick/mount.

This patch fixes by setting identity string at openlog() which sets
programname/app-name as similar to old style log file prefixed by
gluster, glusterd, glusterfs or glusterfsd
