runtime options not inherited from 64-bit parent to 32-bit child

_From [bruen...@google.com](https://code.google.com/u/109494838902877177630/) on April 28, 2014 16:03:04_

Running the mixedmode test bin64/drrun -debug -loglevel 3 -early_inject_map -early_inject_location 5 -heap_in_lower_4GB -code_api -- bin64/create_process.exe D:/derek/dr/build_suite/build_debug-internal-32/suite/tests/bin/win32.mixedmode.exe mixedmode

=> child process has no non-default options

related to recent env var inheritance changes?

I would guess it's a regression, must have once worked when this test was being developed: I worked on it and must have had logs
