iotests: rebase qemu_io() on top of qemu_tool()
Rework qemu_io() to be analogous to qemu_img(); a function that requires
a return code of zero by default unless disabled explicitly.
Tests that use qemu_io():
030 040 041 044 055 056 093 124 129 132 136 148 149 151 152 163 165 205
209 219 236 245 248 254 255 257 260 264 280 298 300 302 304
image-fleecing migrate-bitmaps-postcopy-test migrate-bitmaps-test
migrate-during-backup migration-permissions
Test that use qemu_io_log():
242 245 255 274 303 307 nbd-reconnect-on-open
