iotests: Do not suppress segfaults in bash tests
Currently, if a qemu/qemu-io/qemu-img/qemu-nbd invocation receives a segmentation fault, that message is invisible in most cases since the output is generally filtered and bash suppresses the segmentation fault notice for any but the last element of a pipe. Most of the time, the test will then fail anyway because of missing output, but not necessarily (as happened with test 82 recently). Fix this by making the corresponding environment variables point to wrapper functions which execute the respective command in a subshell. Giving options to qemu/qemu-io/qemu-img and path names with spaces were broken for the Python tests; this patch "accidentally" fixes that.
