ref-manual: variables: FIT_KERNEL_COMP_ALG: add lzo

From: Richard Leitner <dev@g0hl1n.net>

OE-Core rev f1257d61b76d027d4ece734439993b6bf4e48907 introduced support
for using lzo as compression algorithm for fitImage contained kernel
images.
This patch adds the corresponding documentation to FIT_KERNEL_COMP_ALG
and FIT_KERNEL_COMP_ALG_EXTENSION.
