profiles: wget: unify wget2 into wget profile (#6551)

According to @rusty-snake[1]:

> Distributions started to replace wget with wget2 (I.e. `wget` and
> `wget2` are the same binary where one of them is a symlink to the
> other).

So move all custom entries (other than `private-bin`) from wget2.profile
into wget.profile and turn wget2.profile into more of a redirect to
wget.profile.
