[Fix] parse_url: don’t treat colon in path as port

[arshidkv12]

Fix parse_url() to avoid treating a colon followed by digits inside the path as a port number.

Before:

$url = '//www.example.com/ddd:65333/';
var_export(parse_url($url));

array (
  'host' => 'www.example.com',
  'port' => 65333,
  'path' => '/ddd:65333/',
)

After

array (
  'host' => 'www.example.com',
  'path' => '/ddd:65333/',
)
