When a file doesn't exist or isn't readable, grep complains as follows,
grep: /proc/cmdline: No such file or directory
grep: /etc/kernel/cmdline: No such file or directory
/proc/cmdline doesn't exist when installing package for an OS image and
/etc/kernel/cmdline may not exist if osbuild doesn't want set custom
kernel cmdline.
Use "-s" to suppress the error messages.
Fixes: 0adb0f4 ("try to reset kernel crashkernel when kexec-tools updates the default crashkernel value")
Fixes: ddd428a ("set up kernel crashkernel for osbuild in kernel hook")
