[PATCH v2 1/2] migration: add build option to support qemu build with qatzip

[you.chen]

In this patch, we added qatzip build option in the meson_options.txt and 
meson-buildoptons.sh to support qemu build with qatzip.
If you installed qatzip and would like to use it for live migration, you could 
use "--enable-qatzip" during configure, it will check qatzip availablility from 
the pkg-config list (Please make sure you correctly set PKG_CONFIG_PATH to 
include qatzip.pc).
If you simply use "configure" or use "configure --disable-qatzip", qatzip will 
not be enabled.
