support/testing/{test_edk2, test_grub, test_iso9660, test_fwts}: fix edk2 download

All EDK2 releases <= edk2-stable202408 can't be fetched from git
anymore due to a missing git submodule as reported by [1].

Usually Buildroot fall-back using https://sources.buildroot.net thanks
to BR2_BACKUP_SITE where a backup of the generated archive is
available. But the BRConfigTest remove BR2_BACKUP_SITE default value
while generating the .config used by runtime tests. See [2].

Replace the BR2_BACKUP_SITE override from BRConfigTest in order to
continue testing EDK2 package using the usual backup site.

This workaround needs to be removed with the next EDK2 version bump
using this commit [3].
