Fabrice Fontaine ec1c348b4f build: Add reallocarray to missing.h
reallocarray has been added to glibc relatively recently (version 2.26,
from 2017) and apparently not all users run new enough glibc. Moreover,
reallocarray is not available with uclibc-ng. So use realloc if
reallocarray is not available to avoid the following build failure
raised since commit 891b78e9e8:

/home/giuliobenetti/autobuild/run/instance-3/output-1/host/lib/gcc/xtensa-buildroot-linux-uclibc/10.3.0/../../../../xtensa-buildroot-linux-uclibc/bin/ld: src/sae.o: in function `sae_rx_authenticate':
sae.c:(.text+0xd74): undefined reference to `reallocarray'

Fixes:
