fs-tests: integck: srink file_info structure even more
The 'check_run_no' field does not have to be 64-bit, it can be
32-bit instead and we can save 4 bytes per object. Actually, it
could also be 16-bit, and we could make link_count 16-bit as well,
but that would need a bit more work.
Turn "int checked" flag into 'char' flag to lessen memory
consumption a bit. Indeed, the test allocates a lot of these
data objects, so the size decrease from 36 to 32 bytes on
32-bit platforms is good to have.

When reading and writing OOB we specify the address as absolute
offset from the beginning of the MTD device. This offset is
basically an absolute page offset plus the OOB offset. And it does
not have to be aligned to the min. I/O unit size (NAND page size).
So fix the 'do_oob_op()' function and remove incorrect checking
that the offset is page-aligned. This check leads to the following
errors:
libmtd: error!: unaligned address 2, mtd0 page size is 2048
But obviously, the intent was to write to offset 2 of the OOB area
of the very first NAND page.
Instead of that incorrect check, we should check that the OOB offset
we write to is within the OOB size and the length is withing the OOB
size. This patch adds such check.
