gitweb: Move generating page title to separate subroutine 

get_page_title subroutine is currently used only in git_header_html.
Nevertheless refactoring title generation allowed to reduce indent
level.

It would be used in more than one callsite in the patch adding caching
activity indicator to gitweb.
