Joseph Myers bc688c1029 Fix __ASSUME_SENDMMSG issues (bug 16611). 
Similar to the issues for accept4 and recvmmsg, __ASSUME_SENDMMSG is
also confused about whether it relates to function availability or
socketcall operation availability, and the conditions for the
definition are always wrong (sendmmsg appeared in Linux kernel 3.0,
not 2.6.39); this is now bug 16611.

This patch splits the macro into separate macros like those for
accept4 and recvmmsg, defining them for appropriate kernel versions.

Tested x86_64, including that disassembly of the installed shared
libraries is unchanged by this patch.

	[BZ #16611]
	* sysdeps/unix/sysv/linux/kernel-features.h
	[__LINUX_KERNEL_VERSION >= 0x030000 && __ASSUME_SOCKETCALL]
