executor: prevent "NMI handler took too long" messages
nmi_check_duration() prints "INFO: NMI handler took too long" on slow debug kernels.
It happens a lot in qemu, and the messages are frequently corrupted
(intermixed with other kernel output as they are printed from NMI)
and are not matched against the suppression in pkg/report.
This write prevents these messages from being printed.
