[OE-core] [PATCH] initramfs-framework/setup-live: quote bootparam_root variable

[California Sullivan]

When bootparam_root was empty the if statement would resolve into
invalid syntax instead of short circuiting after the -z, causing a boot
failure.

I stupidly didn't test an empty root parameter with my previous patch
and just assumed the -z $bootparam_root would still work. I was wrong.

Rest assured this patch was tested with all three cases: an empty root
parameter, root=/dev/ram0, and a valid PARTUUID.
