Serge Pavlov 4bc0562719 Driver tests: set --sysroot="" to support clang with DEFAULT_SYSROOT ...

When testing clang that has been compiled with `-DDEFAULT_SYSROOT` set to some path,
some tests would fail. Override sysroot to be empty string for the tests to succeed
when clang is configured with `DEFAULT_SYSROOT`.
