bug#42856: match-error /sys/kernel/debug upon reconfiguring system

[maxim.cournoyer]

Hello,

I've had this error twice (the first time during a local 'guix system
reconfigure', the second time during a 'guix deploy').

The exception looks like this, as reported by 'guix deploy':

--8<---------------cut here---------------start------------->8---

I think it only occurs once (the following 'guix system reconfigure' on
the same machine do not seem to suffer from that error).

This has been covered here: https://issues.guix.gnu.org/42826.
