rework systemd's own process environment handling/passing
Stop importing non-sensical kernel-exported variables. All parameters in the kernel command line are exported to the initial environment of PID1, but suppressed if they are recognized by kernel built-in code. The EFI booted kernel will add further kernel-internal things which do not belong into userspace. The passed original environ data of the process is not touched and preserved across re-execution, to allow external reading of /proc/self/environ for process properties like container*=.
