Subject: [PATCH] Add clone3-workaround wrapper to support Docker < 20.10.10

See https://github.com/openmaptiles/openmaptiles/issues/1719

openmaptiles claims to support Docker >= 1.12.3 but GLIBC >= 2.34
we need Docker >= 20.10.10 and openmaptiles/openmaptiles-tools
currently uses Debian 12 as base OS that uses GLBC 2.36.
