Don't call GetFileVersionInfo(), which calls LoadLibrary() to be able to
access the module's resources. Loading modules from the crashy process
into the handler process can cause trouble. The Crashpad handler
definitely doesn't want to run arbitrary modules' module initializer
code.
Since the VS_FIXEDFILEINFO needed is already in memory in the remote
process' address space, just access it from there.
