s390/setup: Add decompressor_handled_param() wrapper

Browse Source 
Make decompressor_handled_param() a wrapper for
__decompressor_handled_param(). __decompressor_handled_param() now
takes two parameters: a function name and a parameter name, which do
not necessarily match.

This allows to use characters like "-", which are not allowed in
function names, for command line parameters which are handled by the
decompressor and should be ignored by the kernel.
