gitweb: Minor visual changes to templates

- Remove cancel button in favor of back button.

- In create/edit form, make the form full width to make it consistent with other
  forms. The styling for all the forms can be changed together, if desired.

- Remove dead HTML code outside block context in inherited template.

- Add missing 'list-group' parent for repository list as suggested by bootstrap.
