elf: Test dlopen (NULL, RTLD_LAZY) from an ELF constructor

This call must not complete initialization of all shared objects
in the global scope because the ELF constructor which makes the call
likely has not finished initialization.  Calling more constructors
at this point would expose those to a partially constructed
dependency.

This completes the revert of commit 9897ced8e78db5d813166a7ccccfd5a
("elf: Run constructors on cyclic recursive dlopen (bug 31986)").
