This patch removes the auto-generation for recvmsg and sendmsg syscall
and adjust the kernel-features.h for all architectures supported on
Linux. This patch follows the idea of 'Adjust kernel-features.h defaults
for socket syscalls.' (35ade9f11b) by define
__ASSUME_SENDMSG_SYSCALL and __ASSUME_RECVMSG_SYSCALL as supported by
default and undefine it for the architecture that do not support it
directly.
The main rationale is to make is easier add code wrapper over the syscall
to fix BZ#16919 (recvmsg standard compliance).
Tested on x86_64, i686, aarch64, armhf, and powerpc64le.
