deprecated_profile_check: suggest portage upgrade

If the new profile can't be parsed due to unsupported EAPI, then show a
warning like this:

!!! Your current profile is deprecated and not supported anymore.
!!! Use eselect profile to update your profile.
!!! Please upgrade to the following profile if possible:
        default/linux/x86/13.0/desktop

!!! Unable to parse profile: '/usr/portage/profiles/default/linux/x86/13.0/desktop'
!!! ParseError: Profile contains unsupported EAPI '5': '/usr/portage/profiles/eapi-5-files/eapi'

 * You must update portage before you can migrate to the above profile.
 * In order to update portage, run 'emerge --oneshot portage'.
