MDEV-39803 RPM dependencies missing from MariaDB-server-galera package

RPM dependencies where not included in cpack build due to incorrect
component name.

Corrects a103be3

Becase the wsrep_info plugin installs as a plugin, it overrites the
cpack_rpm server-galera PACKAGE_DEPENDS.

As such make the cmake/plugin.cmake only sets the PACKAGE_DEPENDS if
not already set. This allows plugin to override automatic REQUIRES,
fine-tuning their own dependencies
