dummy/dummy.c: Fix unaligned access in dummy_get_level()

Browse source 
This fixes an unaligned access in dummy/dummy.c in the function
dummy_get_level() which resulted in crashes (Bus Error) on systems
with stricter alignment requirements such as SPARC.

On x86_64 (and any other architecture with less strict alignment
requirements), the compiler automatically optimizes the memcpy()
out if necessary such that there are no performance issues.
