[Ada] Fix gmem.out corruption by GNAT.Expect
gcc/ada/
* adaint.h (__gnat_in_child_after_fork): New flag to express
child process side after fork call.
* adaint.c (__gnat_portable_spawn): Set flag
__gnat_in_child_after_fork.
* expect.c (__gnat_expect_fork): Set __gnat_in_child_after_fork
to one on child side.
* libgnat/memtrack.adb
(In_Child_After_Fork): Flag to disable memory tracking.
(Allow_Trace): New routine defining if memory should be tracked.
(Alloc, Realloc, Free): Use Allow_Trace in "if" condition
instead of First_Call.
