Rebase kexec-tools to 2.0.11-1

[Dave Young]

Hi,

Simon released 2.0.11 today.

I have rebased Fedora kexec-tools to 2.0.11 as well.
http://koji.fedoraproject.org/koji/taskinfo?taskID=11753009

Please help to do some test, please report in case anything wrong.

BTW, for makedumpfile, Atsushi said there's a problem about kernel 4.2 thus
I'm waiting for his fix.

It will be appreciated someone can test upstream makedumpfile 1.5.9 as well
and check if there's more problem.

Thanks
Dave
