pid1: restore the original environment passed by the kernel when switching to a new system manager

PID1 may modified the environment passed by the kernel when it starts
running. Commit 9d48671c62de133a2b9fe7c31e70c0ff8e68f2db unset $HOME for
example.

In case PID1 is going to switch to a new root and execute a new system manager
which is not systemd, we should restore the original environment as the new
manager might expect some variables to be set by default (more specifically
$HOME).
