Update bdii-slapd-start startup script

[VilleS1]

If both ipv6 and ipv4 addresses are being used the systemd script breaks because of quotes in the options. This is the fix.

Looks like your " Install AlmaLinux 8 RPMs (pull_request) " test is broken. It tries to find packages in wrong url.

Thanks for the PR!
Yep the tests are to be updated, we will look at this.
We need to put in place such an IPv4/IPv6 BDII instance to test your change, and see if we can do something a bit cleaner, personally I'm not fond of the array with bash -c call and the later command execution.

Shell is needed I guess for env (service won't start otherwise) and bash needs an array to not break the quotes so I am interested to see what you come up with. This is on Ubuntu 20.04.06 LTS. Everything needs to work under systemd which is a different thing than running the scripts directly.

Hey @VilleS1. We have decided to merge #51 instead.
I'm closing this -- Thank you very much anyway for the contribution and effort.
