[PATCH next 1/3] CI: use GNU mirror for grub (and switch to HTTPS)

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

GNU announced they activated mirrors for git servers[1] in May this
year.

The main git server keeps being very unreliable and switching to those
mirrors seems to improve reliability (albeit somewhat slow).

Yes, the URL in this patch has nothing in common with the URL in the
linked mail, it was extracted from the Clone section in the mirrored
cgit page[2].

While at it, switch to the HTTPS clone which is "more secure" than git
protocol.
