Add the STACKPROTECTOR symbols to the script that generates the
symbols that should not be removed by the use of LTO when linking
a shared object. This prevents a fail to build due to link errors.

Changes in v2:
- Made the new match more specific and added it to the grep run rather
  than run grep twice
