Add HAVE_MREMAP for mremap usage

Browse Source 
Introduce (only on Linux) and use a HAVE_MREMAP symbol to advertize mremap
availability.

Move the malloc-sysdep.h include from arena.c to malloc.c, since what is
provided by malloc-sysdep.h is needed earlier in malloc.c, before the inclusion
of arena.c.
