reallocarray: a bit more tuning
* lib/reallocarray.c: Include intprops.h.
(reallocarray): Use INT_MULTIPLY_WRAPV instead of
xalloc_oversized, as it now suffices and is likely a bit more
efficient (five fewer machine insns on Ubuntu 20.10 x86-64).
* modules/reallocarray (Depends-on): Depend on intprops, not
xalloc-oversized. Use conditional dependencies to avoid building
realloc-gnu when not needed.
