loader: do not build complex commandline for mb2 kernel
100%
Description
With boot loader environment being passed to kernel, we do not need to build complex kernel command line for MB2 kernel, instead all automatic properties should be passed in environment and only manually set properties should be set on kernel command line.
so this will set kernel command line:
ok boot -B console=ttya
but
ok boot
will keep variables in environment. However, there is one notable exception - if the user did not specify console like above, but there is os_console set in environment, we will pass the "-B console=$os_console" for kernel command line. This exception is because of the nature of os_console variable itself - it was created to distinguish loader console from kernel console.
For multiboot 1 kernels, there are no changes - all properties are set on kernel command line.
