wa2-lava: Install dependency packages on host

Install dependency packages on host side.
install-deps.sh script will look for apt-get lock and install packages
when the lock is free. The advantages of this patch is
  - Do not install if the package is already present
  - Installation should not fail because of parallel installation of packages
  - if apt-get is already locked wait 5 sec and try installation again
       till it get successful
