Fixes two locations where unaligned accesses will cause bus errors on
architectures that are strict about such accesses, namely sparc.

The first is in swab32_into, which is called with an offset of +1 into
an unsigned char array from mklink_fs.

The second is in add2fs_from_tarball when checking the validity of a
tarball, which casts a string from an unaligned position inside a struct
to a long.

After these changes, the test suite passes on sparc.
