Konstantin Belousov 1005d3d053 rtld: fix dlopen() for an object that is already mapped but not yet initialized 
For instance, dso might be mapped as needed but not yet initialized from
the other subtree of needed objects, while current object' constructor
does dlopen() for the dso.  Right now rtld does relocations and other
processing based on the arrival of new objects in the global list, which
is not happens there.  Directly check for the initialization state of
the object, for which we would return the handle.

One practical use case of this support is e.g. dlopen("libthr.so",
RTLD_NOLOAD) by libraries that are threading-aware but happy to live
with libc pthread shims if the program is not multithreaded.
