Subject: [PATCH] build(server): make perl-DB_File a weak dependency of
 xCAT-server

perl-DB_File is only used by the Confluent client
(lib/xcat/Confluent/Client.pm). EL10 dropped libdb, EPEL re-adds it only
on its own architectures, and riscv64 has no perl-DB_File at all, so a
hard Requires makes xCAT-server uninstallable on a riscv64 management
node. Ask for it weakly: dnf installs it where it exists and skips it
where it does not; the Confluent client stays optional.

The dependency generator also turns Confluent/Client.pm's "use DB_File"
into a hard perl(DB_File) requirement regardless of the Recommends, so
that one generated requirement is excluded as well, appended to whatever
filter the build root already set.

Weak dependencies need rpm 4.12, so both only apply on a build host that
has it (EL8 and later, or SUSE 15 and later); older build hosts keep the
hard requirement they have today.
