Julius Werner 5779ca718c cbfstool: Replace FILENAME_ALIGN 16 with ATTRIBUTE_ALIGN 4
cbfstool has always had a CBFS_FILENAME_ALIGN that forces the filename
field to be aligned upwards to the next 16-byte boundary. This was
presumably done to align the file contents (which used to come
immediately after the filename field).

However, this hasn't really worked right ever since we introduced CBFS
attributes. Attributes come between the filename and the contents, so
what this code currently does is fill up the filename field with extra
NUL-bytes to the boundary, and then just put the attributes behind it
with whatever size they may be. The file contents don't end up with any
alignment guarantee and the filename field is just wasting space.

This patch removes the old FILENAME_ALIGN, and instead adds a new
alignment of 4 for the attributes. 4 seems like a reasonable alignment
to enforce since all existing attributes (with the exception of weird
edge cases with the padding attribute) already use sizes divisible by 4
anyway, and the common attribute header fields have a natural alignment
of 4. This means file contents will also have a minimum alignment
guarantee of 4 -- files requiring a larger guarantee can still be added
with the --alignment flag as usual.
