More fixes for occasional CI test based on new failures (#6131)

* Need utf8 in locale-gen to get that encoding by default

* Run R CMD check manually if 'rcmdcheck' unavailable'

* smaller diff

* if/else, not ifelse

* Exclude old macOS versions

* Install packages required for other.Rraw

* need to install curl manually?
