Added 'wget' as a dependency

'wget' is a dependency as without this additional components won't download as part of initial install, one such example is;
```
wget -O /ail-framework/ardb/src/../deps/jemalloc-5.1.0.tar.bz2 https://github.com/jemalloc/jemalloc/releases/download/5.1.0/jemalloc-5.1.0.tar.bz2 && \
```
