Even though systemd-networkd and systemd-udevd do not support ConditionSecurity= in .network, .netdev, and .link files, the unified condition_test() function maintained a function pointer table that unconditionally referenced condition_test_security(). Consequently, linker garbage collection (--gc-sections) could not drop the security test code, inadvertently pulling in dlopen dependencies and ELF notes for apparmor, audit, and tpm2 libraries into these binaries. To resolve this, introduce condition_test_net() and condition_test_list_net(), which utilize a trimmed-down function pointer table that excludes security-related condition evaluators. By migrating networkd and udevd to these new network-specific variants, the reference to condition_test_security() is completely severed in their dependency chains. This allows the compiler and linker to successfully garbage-collect the unused security logic and safely drops the unnecessary dlopen notes from those binaries.
