genext2fs is built only if the user selected an ext2 root filesystem.
However, some use-cases can't live with the full target/ dir on the
root filesystem, and requires separate partitions (eg. for /usr).
In this case, the user would not select an ext2 root fs in the
Buildrooot menu, and would only generate a tarball of the rootfs.
This tarball would then be used from a post-image script to build
the actual required FSes.
But then, genext2fs is not built, since the ext2 root FS was not
selected.
As for the other filesystem generators, provide a host variant of
genext2fs (genext2fs is already host-package aware, so only needs
adding a Kconfig entry).

Some bootloaders have a buggy ext2 support, and require ext2 rev1
instead of the traditional ext2 rev0 that genext2fs produces.
tune2fs accepts only one '-O list' at a time, so we need to construct
a list of -O options.

Use the host-e2fsprogs to tune2fs the generated rootfs.ext2 image,
and upgrade it to either one of ext2, ext3 or ext4.
Since calling tune2fs may require running e2fsck (tune2fs will warn
to do so when certain FS options are changed), we systematically call
e2fsck. This makes the code path simpler, and as a side-effect checks
that genext2fs did not generate garbage.
In turn, e2fsck will unconditionally add a UUID to the filesystem,
which is bad for reproducibility, so we call tune2fs again to remove
the UUID. This does not require checking the filesystem.
To ensure compatibility of Buildroot's .config, leave ext2 as the
default. Boards' .config can override this at will.

Use a 'if...endif' construct instead of repeating the
'depends on' for each symbols.

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.

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