gitweb: tree view: eliminate redundant "blob"

Binary and non-binary blobs:

The "list" table element of tree view is identical
to the "blob" link part of the link table element.
I.e. clicking on "blob" is identical to clicking on
the entry itself.

Thus, eliminate "blob" from being shown -- the user
can get identical result by simply clicking on the
entry itself.
