Consider some defconfig changes for busybox

[cwixon@…]

I'm copying over my comment #3 from #1116, since the basic statement of that
bug is indeed fixed, and this was added later:

The default set of utilities configured by busybox could stand to be
updated. In 1.9.1, the latest version in the OE repository (and in earlier
versions), the provided (default) defconfig specifies:

• no 'nice' command (but 'renice' is there);

• 'xargs' doesn't support the '-0' flag (even though 'find' has '-print0'); and

• 'find' doesn't have the '-delete' expression

Other changes might also be useful, so I'd encourage a thorough re-evaluation of
all of the default options by someone who knows their stuff.

And to fix part of another bug I submitted (that would be #870), I
personally would set "CONFIG_INSTALL_NO_USR=y" so people can mount a memory card
partition at /usr and still allow the boot/init process to complete successfully
without it.

Change to enhancement.
