Introduce regression tests for various qemu failures.

Test failure of qemu and recovery of the library:
 - mid-command
 - between commands
 - during launch [test not working yet]
 - explicitly killed by guestfs_kill_subprocess

Also this patch cleans up the other tests in this directory
and disables the long-winded test-bootbootboot test.
