arch: x86: Always set the bootloader type

Browse Source 
We set it to 0xff, which is for unregistered loaders.
The kernel checks that the bootloader ID is set when e.g. loading
ramdisks, so not setting it when we get a bootparams header from the
loader will prevent the kernel from loading ramdisks.

Fixes: #918
