So that users of regulars/starterkits do not download with ftp.altlinux.org

Required by shaba@:
https://bugzilla.altlinux.org/show_bug.cgi?id=41588#c1

Made by analogy with features.in/repo/image-scripts.d/90-enable-repo.

This variable blocks the enable of online repositories and activates
the enable of RPMS.main repository in iso or rootfs.
The old name was misleading.

Default changed from yandex to alt due to:
https://bugzilla.altlinux.org/show_bug.cgi?id=41588#c1

It is not possible to install packages with puppet if aptitude is installed.

This created the problem of checking all the images by the command:
make CHECK=1 everything

The problem was earlier bacause of that the with /etc/os-release
package was installed too early.

All distributions and starterkits switched from refind to grub-efi
a year ago. Sorry for not noticing that alt-server is still using
rEFInd.

make-aptbox is needed to check package lists only.

The opensbi-1.0-alt1.riscv64.rpm package supports Unleashed, Unmatched,
Nezha, Lichee RV. Thanks sbolshakov@
The u-boot-sifive-2022.01-alt1.riscv64.rpm package supports Unleashed
and Unmatched. U-Boot SPL has been buided for Unleashed,
now bootloading both boards similar.

systemd-utils-standalone no available for p9.
apt-conf-ignore-systemd guarantees the installation of
systemd-utils-standalone.

This will allow for ISO, writed on flash, disable gfxterm and
enable serial console, if necessary. For EFI only.

Example:
GRUB_TERMINAL='console serial'
GRUB_SERIAL_COMMAND='serial --unit=0 --speed=115200'

Needed for support flatpak.

For systemd needed /etc/syscofig/mouse from startup.

This will allow:
- When bootloading, set 'console=' to gain access to the sequential console.
  Needed for SBC and QEMU.
- When you bootload to receive a ready-to-work environment for
  building rpm-packages and images for other architectures with
  hasher + qemu-static.

For systemd not needed livecd-qemu-arch. systemd-binfmt.service makes
all the work.

When building the rpm package .gitignore is deleted. These files
are necessary in order for saved profiles when building the image
from git repository and from installed rpm package have been
identical.

Also:
- added ~/.mkimage/profiles.mk for use this apt.conf's from
  mkimage-profiles with variable BRANCH.
- use local cache packages in ~/apt/ for to reduce the time of
  repeated builds.
- use mirror yandex, because faster
- repo ports is not signed.
