Andres Amaya Garcia 9b04e19129 Use grep to detect zeroize test failures on GDB
This patch uses grep to search the GDB output for errors as there is
a bug in the tool that causes it to return 0 to the system even though
there was a problem in the script.

This patch also fixes the zeroize test to work with the --keep-going
option in all.sh.
