fix(xcat-core): drop RHEL-only perl build deps on SUSE

The perl-xCAT component specs BuildRequire perl-Pod-Html and (in
xCAT-client) perl-generators, neither of which exists on openSUSE/SLES,
so rpmbuild aborts at dependency resolution before the build can start.
perl-generators is a RHEL/Fedora-only helper that emits perl dependency
metadata; SUSE's rpm generates those itself. Pod::Html ships inside the
core perl package on SUSE, with no separate perl-Pod-Html subpackage to
require. Guard both BuildRequires with %if !0%{?suse_version} so the SUSE
build resolves while EL/Fedora builds are unchanged.
