Mask Linux thermal interrupt info in /proc and /sys

[giuseppe]

Issue Description

we need the equivalent of moby/moby#49560 for Moby.

The paths /proc/interrupts and /sys/devices/system/cpu/<cpuX>/thermal_throttle must be masked by default.

The main difficulty is that /sys/devices/system/cpu/<cpuX>/thermal_throttle is not a static value but it depends on the number of cpus on the current system, so we need to make sure it doesn't break the current unmasking mechanism we have in place.
