openssh/dropbear: No need for each to PROVIDE ssh/sshd
Nothing in the system actually uses the PROVIDES field for these
recipes, its usually the runtime packages that are used. We can
therefore remove the PROVIDES and hence quieten the associated
warnings from bitbake.
If these recipes do really need the PROVIDES, they would be better
as virtuals and adding that to MULTI_PROVIDER_WHITELIST.
