gitweb: Move 'lineno' id from link to row element in git_blame

Move l<line number> ID from <a> link element inside table row (inside
cell element for column with line numbers), to encompassing <tr> table
row element.  It was done to make it easier to manipulate result HTML
with DOM, and to be able write 'blame_incremental' view with the same,
or nearly the same result.
