This turns out to be a problem with the
linux-headers-5.13.0-trunk-common package.

zfs-dkms's configure runs the following:
KBUILD_MODPOST_NOFINAL= KBUILD_MODPOST_WARN= make modules -k -j64 -C /lib/modules/5.13.0-trunk-amd64/build M=/var/lib/dkms/zfs/2.0.3/build/build/conftest >build/conftest/build.log 2>&1

That output log file contains:

  CC [M]  /var/lib/dkms/zfs/2.0.3/build/build/conftest/conftest.o
sh: 0: cannot open /usr/src/linux-headers-5.13.0-trunk-common/scripts/modules-check.sh: No such file
make[1]: *** [/usr/src/linux-headers-5.13.0-trunk-common/Makefile:1796: modules_check] Error 2
make[1]: Target 'modules' not remade because of errors.
make: *** [/usr/src/linux-headers-5.13.0-trunk-common/Makefile:232: __sub-make] Error 2
make: Target 'modules' not remade because of errors.
make: Leaving directory '/usr/src/linux-headers-5.13.0-trunk-amd64'

It turns out the modules-check.sh file is missing from the headers
package.
