test-runner: set msize to remove runtime warning 

Newer QEMU version warn that msize is set too low and may result
in poor IO performance. The default is 8KiB which QEMU claims is
too low. Explicitly setting to 10KiB removes the warning:

qemu-system-x86_64: warning: 9p: degraded performance: a
reasonable high msize should be chosen on client/guest side
(chosen msize is <= 8192).
See https://wiki.qemu.org/Documentation/9psetup#msize for details.
