configs: update openEuler 24.03 LTS chroot to SP4 and fix source metalink

Bump the openEuler 24.03 LTS template from SP1 to SP4 (releasever,
description, bootstrap_image). module_platform_id stays platform:oe2403.
SP4 is now registered in the metalink (mirrormanager) endpoint the
chroot relies on, and the docker tag 24.03-lts-sp4 is published on
Docker Hub.

Also fix the source and update-source metalink repositories across all
openEuler templates (20.03, 22.03, 24.03): the path= metalink form does
not translate the $releasever dnf variable into the full mirror
directory name (only the repo= form does), so path=openeuler/$releasever
resolved to a non-existent path and silently broke mock --sources.  Use
the literal openEuler-<version> directory name instead.
