ext2fs: Translate the EXT4_EXTENTS and EXT4_INDEX to the inode flags.

r260545 cleared the inode flags to fix corruption problems but
we still need to pass some EXT4 flags for the ext4 read-only
mode.  None of these attributes has an equivalent in FreeBSD and
are uninteresting for the system utilities so they should be
innaccessible in ext2_getattrib().

Note: we also use EXT4_HUGE_FILE but we use it directly from the
dinode structure so it is not necessary to translate it,

Remove trailing whitespace.
Remove INCSDIR variable which is only used in elftoolchain's own build
framework.
Reapply revisions r237528, r237531 and r238741 which make libelf
properly include sys/ headers from the source tree instead of the
host.

These patches are also applied to libdwarf since libdwarf requires
the same sys/ headers as libelf.
