BUG/MINOR: mworker: fix typo in chroot error message

Since its introduction in 1.8 with commit 095ba4c24 ("MEDIUM: mworker:
replace systemd mode by master worker mode"), it says "cannot chroot1(...)"
which seems to be a leftover of a debug message. It could be backported but
probably nobody will notice.
