[SYCL] Fix DAE by avoiding creation of obsolete device images

Due to an unintentional copy of the RTDeviceBinaryImage object that
was happening in ProgramManager::build(), the NativePrograms map
was getting populated by an extra entry. No duplicating entry was
being created in the m_EliminatedKernelArgMasks, which made the
image-based lookup in ProgramManager::getEliminatedKernelArgMask()
exit early. The returned empty KernelArgMask led to errors during
kernel argument setting whenever several native programs were created
(e.g. for `kernel_bundle` or device code split use cases).

Tested in intel/llvm-test-suite#575.
