Do not call art-on macro by default.

If you are debugging a native process, SIGSEGV gets ignored by default.
The gdbclient bash function has been modified to only call the art-on
macro when running gdbclient app_processXX.

Also, print a warning in case someone is trying to debug a native
process using app_process.
