[Gc] Late definition of feature macro in dyn_load.c

I currently get a compilation error on Linux due to dl_phdr_info being
used undefined in dyn_load.c.  The reason is that the inclusion of
private/gc_priv.h, which includes the required system header, is placed
after the definition of the _GNU_SOURCE feature macro.

* dyn_load.c: Move inclusion of private/gc_priv.h below definition of
feature macro.
