Ext2FS: Make Ext2FSInode::is_directory() fast

Browse Source 
This patch overloads Inode::is_directory() with a faster version that
doesn't require instantiating the whole InodeMetadata.

If you have an Ext2FSInode&, calling is_directory() should be instant
since we can just look directly at the raw inode bits.
