kdumpctl: status function cleanup

Move the code to check /sys/kernel/kexec_crash_loaded to function
check_kdump_feasibility(). And rename status() to check_current_kdump_status()
so these two functions become clearer.

cleanup kdumpctl status path as well.

Tested with kernel without CONFIG_KEXEC
Tested with run kdumpctl start two times.
