The pre runtime scriptlet returns false exit status on some installations

Description of problem:
On the installation of live ISO of "AlmaLinux OS 8 and 9 MATE" the process crashes while executing of pre runtime scriptlet of the openvpn package.

The purpose of this scriptlet is "if they not exist, create a group and an user with name of openvpn"

Seems like the scriptlet returns the false exit status even it succeeds. 


As we see from the examples below, the pre scriptlet has exit 0 at the end.

- https://gitlab.com/redhat/centos-stream/rpms/httpd/-/blob/c9s/httpd.spec?ref_type=heads#L632-637
- https://gitlab.com/redhat/centos-stream/rpms/postfix/-/blob/c9s/postfix.spec?ref_type=heads#L545-555
- https://gitlab.com/redhat/centos-stream/rpms/nginx/-/blob/c9s/nginx.spec?ref_type=heads#L462-467

After adding "exit 0" for openvpn package too, the installation finishes successfully and a group and an user is created with "openvpn" name.

How reproducible:

Create live ISO of AlmaLinux OS 8 with MATE desktop envoriment.

1. git clone https://github.com/AlmaLinux/sig-livemedia.git
2. Prepare the Build Environments as mentioned the repo above.
3. Build

AlmaLinux OS 8:
sudo livemedia-creator \
    --ks=kickstarts/almalinux-8-live-mate.ks \
    --no-virt 
    --resultdir ./iso_mate_8 \
    --project 'AlmaLinux Live' \
    --make-iso \
    --iso-only \
    --iso-name AlmaLinux-8.8-x86_64-Live-MATE.iso \
    --releasever 8.8 \
    --volid 'AlmaLinux-8_8-x86_64-Live-MATE' \
    --nomacboot

AlmaLinux OS 9:
sudo livemedia-creator \
    --ks=kickstarts/almalinux-9-live-mate.ks \
    --no-virt 
    --resultdir ./iso_mate_9 \
    --project 'AlmaLinux Live' \
    --make-iso \
    --iso-only \
    --iso-name AlmaLinux-9.2-x86_64-Live-MATE.iso \
    --releasever 9.2 \
    --volid 'AlmaLinux-9_2-x86_64-Live-MATE' \
    --nomacboot

Actual results:
Non interactive installation failed: DNF error: Error in PREIN scriptlet in rpm package openvpn.


Expected results:
1. Successful installation without any warning or error output.
2. Group and User created with "openvpn" name.

Seems like due lack of permission, I cannot push the fix back to my fork on https://src.fedoraproject.org/fork/elkhan/rpms/openvpn to create a PR.
