payloads: Add an option to compress secondary payloads

Browse Source 
Both GRUB and SeaBIOS can chainload lzma compressed payloads.
Therefore it is beneficial to compress secondary payloads
like Memtest86+, coreinfo, nvramcui,... for both size reasons and
often also speed reasons since the limiting factor is generally the
IO of the boot device.

Tested with SeaBIOS and memtest86+ master on Thinkpad X220.
