godoc: use shorter titles for tabs

Browse Source 
In a browser with many open tabs, the tab titles become short
and uninformative because they all start with the same prefix
("Package ", "Directory ", etc.).

Permit use of shorter tab titles that start with the relevant
information first.

Fixes #3365.
