Symlinks to directories are ignored when processing feature files

If some myfeature.files includes a path which is a symlink to a directory, we would expect that symlink to be included in the initramfs. At present, however, it is not due to the checks in feature_files():

				for file in $glob; do
					if [ -d $file ]; then
						find $file -type f
					elif [ -e "$file" ]; then
						echo $file
					fi
				done

The [ -d $file ] check returns true: a symlink to a directory is essentially a directory; however, find $file -type f echoes nothing. We would like these symlinks to fall through to the [ -e "$file" ] case, where the symlink is echoed as we desire.

A fix is to replace if [ -d $file ]; then with if [ -d $file ] && [ ! -L $file ]; then
