neotest: info-local: Fix it when CPU frequence/idle information is not available

For example under KVM it was failing as

    cpu:	Intel(R) Xeon(R) CPU E5-2678 v3 @ 2.50GHz
    cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq: No such file or directory

        print '%.2fGHz' % ( / 1E6)

-> Fix it by checking whether cpufreq/cpuidle directories are available, and display "?" if they are not.
