Utils: Fix error prone default value of appendOrSet

It was not readily clear that Environment::appendOrSet/prependOrSet
needed a value for "sep", otherwise it would just concat the values without separator. This got apparent when looking at usages of
appendOrSet.

Instead there are now three options, "Auto", "Colon" or "Semicolon"
with the default being "Auto", which determines the separator based on
the Environment::OsType.

Usages of appendOrSet and prependOrSet are also fixed with this commit.
