libselinux / libsemanage: work around FD_CLOEXEC and SOCK_CLOEXEC absence

[ CQID: WIND00438478 ]
[ CQID: WIND00439485 ]

Turns out some of the truly old hosts don't even really recognize
FD_CLOEXEC and most of the older ones don't know about SOCK_CLOEXEC.  Work
around each (define FD_CLOEXEC to something sensible, simply don't use
SOCK_CLOEXEC, produce warnings in either event).

+Subject: [PATCH 3/3] libsemanage: define FD_CLOEXEC as necessary
+
+In truly old systems, even FD_CLOEXEC may not be defined.  Produce a
+warning and duplicate the #define for FD_CLOEXEC found in
+asm-generic/fcntl.h on more modern platforms.
