Align wait-for-it host with libreoffice start command

[fetwar]

libreoffice start command uses the loopback address 127.0.0.1 instead of localhost.

This can cause issues in resolving to the correct address if:

• The host machine uses external DNS resolution only and Docker DNS is not explicitly set.
• /etc/nsswitch.conf is set to not check local files first.
• The Docker DNS resolution is set for external name resolution only.

This ensures that regardless of DNS resolution issues on the host machine, the container will be able to run, since it doesn't really need these anyway.

Please note, tests failed after the last commit ~3 months ago, I tried to fix this issue as well, but the Github actions logs have expired.

Had problems with rest-api not starting up and

127.0.0.1	localhost
::1	localhost ip6-localhost ip6-loopback

in containers /etc/hosts.

Workaround until this is merged:

docker run --rm --sysctl net.ipv6.conf.all.disable_ipv6=1 libreofficedocker/libreoffice-unoserver:3.18

@fetwar Totally agree with this, anyway apologies for the wait.

The build only failed for the Alpine 3.19, the older releases are fine.

Will take a look at 3.19 later.
