tool/boot: add chain_loader 'unzip'

Browse Source 
'unzip' can uncompress and load raw multiboot images and ELF files.

Usage together with the PXE bootloader ease life running the muen hypervisor
together with a Genode/x86_64 VM, where the raw boot image is typically quite
large.

:'unzip'
The 'unzip' tool is part of the 'morbo' toolchain available under GPL.
The toolchain was obtained from https://github.com/TUD-OS/morbo.
For Genode the unzip was modified so that raw binary images with a Multiboot
OS header can be loaded.
The changes are available on the genode_bender branch of
https://github.com/skalk/morbo.git.
