To use a newer e2fsprogs what you want is _not_ a newer libguestfs,
but a newer e2fsprogs.  So you might try compiling the e2fsprogs
source RPM from CentOS 8 on CentOS 7, ie.
rpmbuild --rebuild e2fsprogs-1.45.6-1.el8.src.rpm

Source packages can be found under here:
https://vault.centos.org/8-stream/BaseOS/Source/SPackages/

Once that is installed on your host, supermin will pick it up.

Rich.
