condition: split condition_test_list() to minimize dlopen dependencies

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.
