Enhance _exclude_scratch_mount_option() function to normalize mount
options. Now it can understand and extract real mount option from
string like "-o opt1,opt2 -oopt3".
And now we do word grep to handle mount options like noinode_cache
and inode_cache.
Finally, allow it to accept multiple options at the same time. No
need for multiple _exclude_scratch_mount_option lines now
