Fix internal error of csp-script-src-self.html?target_hint=_self
This CL fixes the error when running csp-script-src-self.html. The WPT
checks if CSP mechanism blocks the inline script of speculationrules.
However, the WPT uses an inline script to check whether the test fails.
And the blocked event makes a duplicate entry in key-value-store.py
server that doesn't allow duplicated entries. In this CL, allow the
inline script to check the test results and avoid firing unintended
securitypolicyviolation.
