libsepol: make reallocarray check more robust

Browse Source 
Some cross-compiler toolchains dislike the usage of -o /dev/null and fail
with: ld: final link failed: file truncated

As stdin and stdout is already redirected to /dev/null there is
no need for gcc -o /dev/null.

This fixes an Buildroot autobuild failure for libsepol package:
