runqemu: log parameters correctly within testimage

It is not a good idea to mix logging and calls to print() - if the
output is being captured the result can be that the two types of output
are not recorded contiguously; this could be observed if an error
occurred running runqemu from inside testimage:

---------- snip ----------
ERROR: core-image-minimal-1.0-r0 do_testimage: Output from runqemu:
runqemu - INFO - Continuing with the following parameters:

runqemu - INFO - Setting up tap interface under sudo
sudo: a terminal is required to read the password; either use the -S option to read from standard input or configure an askpass helper
runqemu - ERROR - Setting up tap device failed:

MACHINE: [qemux86-64]
FSTYPE: [ext4]
ROOTFS: [/home/paul/poky/poky/build/tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.ext4]
CONFFILE: [/home/paul/poky/poky/build/tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.qemuboot.conf]
---------- snip ----------

What we should see here is the KERNEL, MACHINE, etc. lines appearing
immediately after the "Continuing with the following parameters:" line
as they do when you run runqemu directly. If we put all of the lines
through the logger instead then it works properly.
