Subject: [PATCH] fix: use runtime require for xCAT::DHCP::Backend in dhcpop

The xCAT-server build-readme script runs every tool in share/xcat/tools/
with --help during RPM packaging. At build time perl-xCAT is not installed,
so the compile-time 'use xCAT::DHCP::Backend' aborts before --help can run.

Switch to runtime require inside the remove-operation branch where the
module is actually needed.
