NFS-Ganesha : Export fails on RHEL 7.1

We grep for CONFFILE parameter in "/etc/syconfig/ganesha"
file to find out the path of the ganesha config file.
In RHEL 7.1, this parameter does not exist in the file and
we can't find out the ganesha config file. Export
fails invariably due to this. Changing this pattern to
a more generic one and default it to "/etc/ganesha/ganesha.conf"

This patch is a backport of the fix merged upstream,
http://review.gluster.org/#/c/11594/
