Remove a redundant check of __cplusplus in Symbian-specific .cpp files

(code refactoring)

* extra/symbian.cpp: Remove "#ifdef __cplusplus" as the latter should
be defined (by default) in case of .cpp file.
* extra/symbian/global_end.cpp: Likewise.
* extra/symbian/global_start.cpp: Likewise.
* extra/symbian/init_global_static_roots.cpp: Likewise.
* extra/symbian/init_global_static_roots.cpp
(GC_init_global_static_roots): Adjust indentation.
