Reinstate compatibility with older Linux with no getrandom()

Browse source 
Commit 42d8b2b1 "Remove legacy FreeBSD compatibility code" removed
compatibility with old versions of FreeBSD, but also removed
compatibility with old versions of Linux and glibc, which was requested
in #833.

This partially reverts commit 42d8b2b167.

Resolves: #833
