xccdf_org.ssgproject.content_rule_service_rngd_enabled tries to enable and start rngd service without installing rng-tools if missing.

Remediation shell script shows:
```bash
# Remediation is applicable only in certain platforms
if [ ! -f /.dockerenv ] && [ ! -f /run/.containerenv ]; then

SYSTEMCTL_EXEC='/usr/bin/systemctl'
"$SYSTEMCTL_EXEC" unmask 'rngd.service'
"$SYSTEMCTL_EXEC" start 'rngd.service'
"$SYSTEMCTL_EXEC" enable 'rngd.service'

else
    >&2 echo 'Remediation is not applicable, nothing was done'
fi
```

and it fails as `rngd.service` is missing. This is solvable by installing `rng-tools` package before enabling the service.
I think this package installation should be part of the remediation.



Reproducible: Always

Steps to Reproduce:
1. ensure rng-tools is not installed
2. Run scap with `OSPP - Protection Profile for General Purpose Operating Systems` profile
3. Try to remediate xccdf_org.ssgproject.content_rule_service_rngd_enabled rule
Actual Results:  
Remediation fails due to missing rng-tools package

Expected Results:  
Remediation succeed.
