Kernel+Toolchain: Use .init_array
section for global constructors
Before this change, our dynamic linker's global constructor handler relied on the GNU linker implicitly including the content of `.ctors` section inside `.init_array`. The mold linker does not do this, so global constructors would fail to be called in the mold-built userland. There is no point in sticking to `.ctors`, as most other systems already use the superior `.init_array` scheme. This commit changes the kernel linker script to not discard this new section, and enables it by default in our toolchain.
