Resolves: BZ1484945
https://bugzilla.redhat.com/show_bug.cgi?id=1484945
Currently the kdumpctl script doesn't handle
whitespaces (including TABs) which might be there before
an option name in the kdump.conf
This patch addresses this issue, by ensuring that the
kdumpctl errors out in case it finds any stray space(s)
or tab(s) before a option name.
