[PATCH v2] increase makdumpfile default message level to 7

[Lianbo Jiang]

Currently, the makedumpfile option '--message-level' is set to 1 when
dumping the vmcore, it only displays the progress indicator message,
but there are no common message and error message, it is important to
report some additional messages, especially for the error message,
which is very useful for the debugging.

In view of this, let's change the message level to 7 by default.
