Jeff Cody ecfa185400 qemu-iotests: _cleanup_qemu must be called on exit
For the tests that use the common.qemu functions for running a QEMU
process, _cleanup_qemu must be called in the exit function.

If it is not, if the qemu process aborts, then not all of the droppings
are cleaned up (e.g. pidfile, fifos).

This updates those tests that did not have a cleanup in qemu-iotests.

(I swapped spaces for tabs in test 102 as well)

# Tests oVirt-like storage migration:
# - Create snapshot
# - Create target image with (not yet existing) target backing chain
# (i.e. just write the name of a soon-to-be-copied-over backing file into it)
# - drive-mirror the snapshot to the target with mode=existing and sync=top
# - In the meantime, copy the original source files to the destination via
# conventional means (i.e. outside of qemu)
# - Complete the drive-mirror job
# - Delete all source images
