fix(cmake): anchor the macOS guest address space for all full-emulator tests
Every target created by add_kyty_full_emulator_test links against the
full kyty_emulator sources, so it drags in the same 620 GiB .zerofill
guest address space segments as the emulator itself. Only the emulator
target and virtual_memory_allocation_tests had the linker flags that
anchor those segments; every other full-emulator test target got the
segments without the anchoring, and the kernel killed them on exec
(posix_spawn EIO / SIGKILL) before main() ever ran.
Move the configure_macos_guest_address_space() call into
add_kyty_full_emulator_test() itself so every target it creates gets
it automatically, and drop the now-redundant explicit call on
virtual_memory_allocation_tests.
