[PATCH v2] miscutils/seedrng.c: fix <sys/random.h> include error on glibc < 2.25

[Thomas Devoogdt]

Hi,

Perhaps the whole function should be rewritten to simply fallback to that
syscall rather than directly fallback to /dev/random?

Or should I replace the define (-1) by that syscall?

Kr,

Thomas
