Hans Ulrich Niedermann d263f5731c Clarify comments on ConditionEnvironment placement
Clarify the comments on ConditionEnvironment= by mentioning that a
ConditionEnvironment= line must be located in the [Unit] section.

The comments suggesting using ConditionEnvironment= themselves are
in the [Service] section, which implicitly and wrongly suggests
that ConditionEnvironment= could be defined right there as well.
