recipetool: create: fix port number parsing issue

A flaw was found when I run:
$ recipetool create "ssh://git@xxx.xxx:7999/xxx.git"

the url turned out to be: "git://git@xxx.xxx/7999/xxx.git;protocol=ssh"
after parsing, the port number was parsed as part of the path, this is
definitely wrong and lead to fetching failures.

This issue could be fixed in reformat_git_uri, by filtering out port
numbers when formatting ":".
