libbinder: build ParcelFileDescriptor on Trusty

Adds ParcelFileDescriptor.cpp to the Trusty build
which in turn compiles some extra related code from
Parcel.cpp. This code uses fcntl(...O_DUPFD_CLOEXEC...)
to duplicate file descriptors which is not available
on Trusty (or other OSes), so we abstract the relevant
calls to that function in a wrapper in OS.cpp.
