kbuild: add image_name to no-sync-config-targets

stable inclusion
from stable-5.10.27
commit ede8be3ae078113fb536159a548890ecc39fbc87
bugzilla: 51493

--------------------------------

[ Upstream commit 993bdde9 ]

'make image_name' needs include/config/auto.conf to show the correct
output because KBUILD_IMAGE depends on CONFIG options, but should not
attempt to resync the configuration.
