Previously, this message used 8193 as the example alternate
superblock. But for most file systems, the backup superblock is
located at 32768 (since most file systems have a block size of 4k, and
not 1k).

Print the actual errors returned by ext2fs_open2() and
ext2fs_check_desc() before we fall back to the backup block group
descriptors so that it's easier to see if there is some obscure
failure that is causing e2fsck to think that it should use the backup
block group descriptors.

The /tmp directory is often a memory based file system, and using this
can speed up running the regression test suite.

E2fsck currently only retries with the backup superblock if the
primary superblock is missing (e.g., overwritten with garbage). If
the superblock is just corrupted enough that it looks like ext2/3/4
superblock, but it is corrupt enough that ext2fs_open2() returns an
error, e2fsck stops without retrying. Let's fix this oversight.
