core: introduce systemd.early_core_pattern= kernel cmdline option
Until a core dump handler is installed by systemd-sysctl, the generation of core dump for services is turned OFF which can make the debugging of the early boot process harder especially since there's no easy way to restore the core dump generation. This patch introduces a new kernel command line option which specifies an absolute path where the kernel should write the core dump file when an early process crashes. This will take effect until systemd-coredump (or any other handlers) takes over.
