[PATCH 0/1] travis.yml: Missing genisoimage package

[Wainer dos Santos Moschetta]

Let's install genisoimage package on Travis build environments so that
the cdrom-test tests run (currently they skip due the missing dependency).

As an example, on
https://travis-ci.org/qemu/qemu/jobs/635375718:

```
MALLOC_PERTURB_=${MALLOC_PERTURB_:-$(( ${RANDOM:-0} % 255 + 1))}
QTEST_QEMU_BINARY=aarch64-softmmu/qemu-system-aarch64
QTEST_QEMU_IMG=qemu-img tests/cdrom-test -m=quick -k --tap < /dev/null |
./scripts/tap-driver.pl --test-name="cdrom-test" 

SKIP
```

Now with this change on
https://travis-ci.org/wainersm/qemu/jobs/635358843:

```
MALLOC_PERTURB_=${MALLOC_PERTURB_:-$(( ${RANDOM:-0} % 255 + 1))}  
QTEST_QEMU_BINARY=aarch64-softmmu/qemu-system-aarch64 QTEST_QEMU_IMG=qemu-img 
tests/cdrom-test -m=quick -k --tap < /dev/null | ./scripts/tap-driver.pl 
--test-name="cdrom-test" 

PASS 1 cdrom-test /aarch64/cdrom/param/realview-eb

PASS 2 cdrom-test /aarch64/cdrom/param/realview-eb-mpcore

PASS 3 cdrom-test /aarch64/cdrom/param/realview-pb-a8

PASS 4 cdrom-test /aarch64/cdrom/param/realview-pbx-a9

PASS 5 cdrom-test /aarch64/cdrom/param/versatileab

PASS 6 cdrom-test /aarch64/cdrom/param/versatilepb

PASS 7 cdrom-test /aarch64/cdrom/param/vexpress-a15

PASS 8 cdrom-test /aarch64/cdrom/param/vexpress-a9

PASS 9 cdrom-test /aarch64/cdrom/param/virt
```
