Submit two old shell scripts: setup_aix.sh and setup_hpux.sh

1. setup_aix.sh was written in 2011.
2. setup_hpux.sh was written in 2012.
The functions of the two scrpts are similar.
They were to help me to initiate a AIX/HPUX environments automatically
to a comfortable working environment.
If you worked on AIX/HPUX before, you would know how it's tough to use
those UNIX OS without do some user configuration and patch some commom
packages :)
