This patch consolidates the send Linux syscall implementation on
sysdeps/unix/sysv/linux/send{to}.c. The changes are:
1. Remove send from auto-generation syscalls.list on the architecture
that uses __NR_send.
2. Define __NR_send for architectures that supports it. It was done instead
of defining in default kernel-features.h because current Linux practice
for new ports are to implement only __NR_sendto [1] and it will
require adding new kernel-features for ports that do not require it
(aarch64 for instance).
3. Remove __ASSUME_SENDTO_FOR_SEND_SYSCALL and decide to use
__NR_sendto for send generation based on __ASSUME_SENDTO_SYSCALL.
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.
