package/cairo: add optional support for lzo

When lzo was compiled before, cairo will use it as optional dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/usr/bin/cairo-sphinx | grep NEEDED | sort
[...]
 0x0000000000000001 (NEEDED)             Shared library: [liblzo2.so.2]

The build system offers no option to en-/disable lzo support:
https://cgit.freedesktop.org/cairo/tree/configure.ac#n54

v2: moved lzo outside BR2_PACKAGE_CAIRO_TEE option (Arnout)
