govc: remove minimum API version check

This check hasn't been useful, except maybe in the early days of govc. It's only caused problems when dev/rc versioning changes in a way that breaks our parsing. Simpler to just remove than to maintain it. Fixes #3643 Signed-off-by: Doug MacEachern <[email protected]>
