boot/grub2: needs host-python3

Browse Source 
When the build host does not have a Python interpreter installed,
host-grub2 is failing to configure due to this missing interpreter.
Note that host-grub2 is the first package to fail because it is a
dependency of grub2. The grub2 target package has the same dependency
requirement.

The issue can be quickly reproduced on a host without Python with the
commands:

    cat <<EOF >.config
    BR2_aarch64=y
    BR2_TARGET_GRUB2=y
    BR2_TOOLCHAIN_EXTERNAL=y
    EOF
    make olddefconfig
    make grub2

grub2 autotools configure.ac search for a Python interpreter since
upstream commit [1] 8b467844e "python: Use AM_PATH_PYTHON to determine
interpreter for gentpl.py", first included in grub v2.04 released
on 2019-07-04. For reference, grub2 has been updated to that version
in commit [2] ea7ec41c "boot/grub2: bump to verson 2.04".

This commit fixes the issue by adding the host-python3 dependency to
host-grub2 and grub2.

Fixes:

    checking for a Python interpreter with version >= 2.6... none
    configure: error: no suitable Python interpreter found
