kdumpctl: Only returns immediately after an error occurs in check_*_modified

Browse Source 
Currently is_system_modified will return immediately when check_*_modified
return a non-zero value, and the remaining checks will not be executed.

For example, if there is a fs-related error exists, and someone changes the
kdump.conf, check_files_modified will return 1 and is_system_modified will
return 1 immediately. This will cause kdumpctl to skip check_fs/drivers_modified,
kdump.service will rebuild the initrd and start successfully, however, any
errors should prevent kdump.service from starting.

This patch will cause check_*_modifed to continue running until an error occurs
or all execution ends.
