[git commit master] find: tweak error message

[Bernhard Reutner-Fischer]

commit: http://git.busybox.net/busybox/commit/?id=2e73d84c02c6dd4945838665ce0167bddbb7f1c8
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

big find:
find: missing argument to `-exec'
we now say
find: -exec requires an argument
instead of the cryptic message we emitted previously.
Additional benefit is that it's now 23 bytes smaller.

Add TODO to add '-exec {} +' support
