Fix sbox_validation_tests & Make isolate_driver.py include the executable itself

This is a redo of https://codereview.chromium.org/1245873002 c6649f2e014a24a909
with fix for Official build.

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.
