vfs101: Fix warning about value truncation

Browse source 
libfprint/drivers/vfs101.c:854:6: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value [-Wabsolute-value]
        if (abs(count - VFS_IMG_BEST_CONTRAST) < abs(vdev->best_clevel - VFS_IMG_BEST_CONTRAST))
            ^
libfprint/drivers/vfs101.c:854:6: note: use function 'labs' instead
        if (abs(count - VFS_IMG_BEST_CONTRAST) < abs(vdev->best_clevel - VFS_IMG_BEST_CONTRAST))
            ^~~
