logging: Change log file name for glusterd

log file names are based on:

 a. user provided input (through -l switch while starting a gluster process)
 b. mount point paths in the case of native clients
 c. volume/configuration files used for starting a gluster process
 d. volume server used for starting a gluster process

Currently glusterd uses scheme c. to have a log file name that reads as

INSTALL_PREFIX-etc-glusterfs-glusterd.log

Since glusterd has a well known configuration file, it does not make much
sense to have log file name based on scheme c. This patch changes the name of
glusterd's log file to "glusterd.log". Hopefully this enables users to identify
glusterd's log file more easily.
