[PATCH] libfs/jffs2: Force the inode size to a non-zero value if a directory.

Set the inode size to 256 to work around a newlib scandir check where a
directory has to have a non-zero size to work. Set the size to greater than
24 bytes, a small dirent size so the allocator in scandir works.

The newlib scandir code should be updated to a more recent scandir from
FreeBSD where these checks have been removed. This change is a work
around to avoid new tools on the release branch.

With this change scandir works on IMFS, RFS and JFFS2.

Closes #3332
