[eudev] [PATCH v2] consistently use #pragma once for header files

[Marcus Folkesson]

Some headerfiles are missing "#pragma once" or corresponding
"#ifndef..." which may result in build error if multiple source files
include the same file.

Use "#pragma once" for all header files.

v2:
	- Convert all #ifndef...  to #pragma once
	- Add *consistently* to patch description
