compiler-rt-netbsd: Add SVN r. 305178

Define GET_LINK_MAP_BY_DLOPEN_HANDLE() for NetBSD on amd64 and i386.

Follow FreeBSD implementation and handle shift of N bytes that
incorporates the map structure.

FreeBSD sets 544 bytes on amd64 of sizeof(Obj_Entry) in linker.
NetBSD sets 608 for amd64 and 324 for i386.
