gitweb: accept trailing "/" in $project_list

The current code is removing the trailing "/", but computing the string
length on the previous value, i.e. with the trailing "/". Later in the
code, we do

  my $path = substr($File::Find::name, $pfxlen + 1);

And the "$pfxlen + 1" is supposed to mean "the length of the prefix, plus
1 for the / separating the prefix and the path", but with an incorrect
$pfxlen, this basically eats the first character of the path, and yields
"404 - No projects found".

While we're there, also fix $pfxdepth to use $dir, although a change of 1
in the depth shouldn't really matter.
