Invert the BR2_PACKAGE_BUSYBOX_HIDE_OTHERS option to use positive logic,
renaming it to _SHOW_OTHERS.
Positive logic is simpler to understand, and it makes all{,package}config
do the right thing.

As discussed earlier on the mailing list. It simplifies code, gives more
sensible error message on typos and makes the defconfigs easier to find
for users.
Furthermore, update documentation to match.
