ldd: do not use dlopen(RTLD_TRACE) for dso when format is specified
Problem is that rtld cannot reliably access updated environment. This was made more obvious by bfd4c875a10560aaa2. The application environment can be in arbitrary state and place, system components can observe it only during execve(2), or in case of rtld, right after execve, when environment is still at know location and format. Instead spawn ld-elf.so.1 in direct exec mode which can correctly read all inherited updates to the environment.
