t/gitweb-lib.sh: drop confusing quotes

Some variables assignments in gitweb_run() look like this:

  FOO=""$1""

The extra quotes aren't doing anything. Each set opens and closes an
empty string, and $1 is actually outside of any double-quotes (which is
OK, because variable assignment does not do whitespace splitting on the
expanded value).

Let's drop them, as they're simply confusing.
