Subject: shred,sort: ensure faster unaligned access to rand module

glibc has changed the public define
from _STRING_ARCH_unaligned to _STRING_INLINE_unaligned as per
https://sourceware.org/bugzilla/show_bug.cgi?id=19462

* gl/lib/rand-isaac.c: Cater for both defines.
* gl/lib/randread.c: Likewise.
* src/system.h: Update commented out code.
