- kiwix-build is installable, so let's install it in travisCI
- Declare the dependency to meson in the setup.py
- As kiwixbuild is installed, we don't need to change the `sys.path`
- Install all packages using travis apt plugin
- Copy ninja binary in $HOME/bin.
We still need sudo required because travis image has more memory in this
case and this is needed to test big cluster in libzim.
There are some problem in meson 0.44.0.
`meson` change the way it detects static libraries (to something that seems
better to me), but it breaks some of our build that we have to fix.
Until we have fixed our dependencies declaration, let's force meson to
be in 0.43.0.
I don't know why, but the travis build doesn't work since few days.
It seems that pip3 cannot install in `/usr/local` anymore.
Probably related to last travis change* as a lot of people seems to have
problem with this update and python (even if this is not the same problems)
Anyway, we should not install a dependencies in global environment without
a sudo. Let's install the pip3 dependencies for the user only.

Make `kiwix-build.py` also fail if sub-command fail instead of just print
an error message and quit.
`kiwix-deploy.py` is far more simple and already fails miserably if a
sub-command fails.
