sandbox: Unprotect DATA regions in bus tests
On my Ubuntu 18.04.1 machine two driver-model bus tests have started
failing recently. The problem appears to be that the DATA region of the
executable is protected. This does not seem correct, but perhaps there
is a reason.
To work around it, unprotect the regions in these tests before accessing
them.
