gitmodules: use 'https://' instead of 'git://'

When you clone the repository without previous commit history, 'git://'
doesn't protect from man-in-the-middle attacks.  HTTPS is more secure
since the client verifies the server certificate.

Also change git.qemu-project.org to git.qemu.org (we control both domain
names but qemu.org is used more widely).
