Jan H. Schönherr 5746f0555d x86/boot: Provide more slack space during decompression 
The current slack space is not enough for LZ4, which has a worst case
overhead of 0.4% for data that cannot be further compressed. With
an LZ4 compressed kernel with an embedded initrd, the output is likely
to overwrite the input.

Increase the slack space to avoid that.
