Commit 99e08650 temporarily removed the post-switch_root chdir (which
points init's working directory at a valid dir in the new root) to test a
spawn hang, and added init-diag SPAWNING/SPAWNED/WAITING eprintlns. The
chdir was never restored: init and every daemon/getty/login/shell it
spawns inherit an invalid CWD (AT_REDOX_CWD_FD), so getcwd() fails in
/usr binaries and interactive shells (zsh/brush) hang instead of reading
input. Restore the chdir and drop the diagnostic eprintlns (which also
spammed the login console).
