Add gdb script to test mbedtls_zeroize()

Browse source 
The gdb script loads the programs/test/zeroize program and feeds it as
imput its own source code. Then sets a breakpoint just before the last
program's return code and checks that every element in memory was
zeroized. Otherwise it signals a failure and terminates.

The test was added to all.sh.
