[8.18] (backport #8896) Fix: Elastic Agent is not enabled on SUSE after installation from RPM package

[mergify]

Presence of init.d files invokes either systemd-sysv-install that may missing on some deployments or results in symlink creation failure.

Tested manually on

• ubuntu, deb install
• redhat 8, rpm install
• suse 15, rpm install

From these 3 only suse was problematic. I was testing other 2 just to rule out breaking behavior.
