package/rng-tools: fix uclibc build

Browse Source 
Fix the following uclibc build failure on aarch64 raised since bump to
version 6.14 in commit 5292d1cf9a and
9070a04adf:

rngd_rndr.c:34:10: fatal error: sys/auxv.h: No such file or directory
   34 | #include <sys/auxv.h>
      |          ^~~~~~~~~~~~

Strangely enough, there is no autobuilder failure for powerpc64le raised
since version bump to version 6.11 in commit
da83261c9b
