sbin/makepkg: resolve failure when source is git url with suffix

Due to the change in 5abefe3, the protocol is not judged as git
anymore, which results in

	==> Retrieving sources...
	  -> Source is https://github.com/axboe/fio.git#tag=fio-3.40
	  -> Downloading fio.git#tag=fio-3.40...

	==> /tmp/stderr <==
	  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
	                                 Dload  Upload   Total   Spent    Left  Speed
	100   162  100   162    0     0    152      0  0:00:01  0:00:01 --:--:--   152
	100  507k    0  507k    0     0   181k      0 --:--:--  0:00:02 --:--:--  658k

The expected behavior is

	==> Retrieving sources...
	  -> Source is https://github.com/axboe/fio.git#tag=fio-3.38
	  -> Cloning fio git repo...
