elf: Initialize GLRO(dl_lazy) before relocating libc in dynamic startup

GLRO(dl_lazy) is used to set the parameters for the early
_dl_relocate_object call, so the consider_profiling setting has to
be applied before the call.

Fixes commit 78ca44da ("elf: Relocate
libc.so early during startup and dlmopen (bug 31083)").
