Revert of Fix sbox_validation_tests & Make isolate_driver.py include the executable itself (patchset #3 id:90001 of https://codereview.chromium.org/1245873002/ )

Reason for revert:
This CL seems to break compile http://build.chromium.org/p/chromium.chrome/builders/Google%20Chrome%20Linux%20x64/builds/3900/.

If the revert doesn't fix it, I will re-land this CL.

Original issue's description:
> Fix sbox_validation_tests & Make isolate_driver.py include the executable itself
>
> Further reduce the boilerplate in .isolate files and is necessary to add debug
> symbols, to be done in a follow up.
>
> Slightly accelerate ninja file parsing by blacklisting more extensions.
>
> sbox_validation_tests wasn't run on Windows since
> https://codereview.chromium.org/1212003003/ (~2 months ago). Thankfully this CL
> uncovered this copy-paste error.
