The generic fs handling does a chmod -R 0:0 $(TARGET_DIR), so there's no
need for a specific option to enforce this when making an ext2fs image.

It's pretty uncommon to use ext2fs on embedded systems, so don't enable
it by default.
Adjust defconfigs to match.

Closes #2929
Instead of just adding a fixed amount to the blocks used, try to
estimate the real space needed according to the filesystem structure
(bitmaps, inodes, blocks).
The side effect of this is that we no longer significantly overestimate
the size needed for small file systems.

With the ROOTFS_TARGET conversion, EXT2_OPTS gets evaluated very early
(before TARGET_DIR is populated with files), so the calculated
blocks/inodes numbers are wrong.
Fix it by moving the calculation to a shell script wrapper around
genext2fs, so it only gets executed just before genext2fs runs.

BR2_TARGET_ROOTFS_EXT2_RESBLKS is an int, so test against 0 rather than
the empty string - Otherwise the test is always true and a -m option
without arguments is added to the argument list, causing genext2fs to
get confused.

The dependency on gzip, bzip2 and lzma are properly handled
automatically. No need to tell the user about this.
