kvm tools: Add option to load disk image read only

As suggested by Christoph Hellwig and Pekka Enberg, Add a '--readonly' flag to
prevent runtime changes to the disk to be saved in the image file. Please note
that since the changes are saved in the VM instead of being written out, a
large amount of modified blocks may kill the tool.

we get this build failure:

kvm-run.c: In function ‘kvm_cmd_run’:
kvm-run.c:119: error: format ‘%lu’ expects type ‘long unsigned int’, but argument 2 has type ‘u64’

Also adjust affected printf format string - this necessiates the use of
the sane Linux definition of u64 instead of the brain-dead int64_t
variant.

That also allows (and necessiates) the removal of the ugly PRIu64 format
string hackery. Friends don't let friends use PRI* hackeries! :-)
