Consolidate Linux recvfrom implementation
This patch consolidates the recvfrom Linux syscall implementation on
sysdeps/unix/sysv/linux/recvfrom.c. The changes are:
1. Define __ASSUME_RECVFROM_SYSCALL by default
2. Undef it for architectures that do not support __NR_recvfrom.
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.
* sysdeps/unix/sysv/linux/alpha/syscalls.list: Remove recvfrom from
auto-generation list.
* sysdeps/unix/sysv/linux/arm/syscalls.list: Likewise.
* sysdeps/unix/sysv/linux/generic/syscalls.list: Likewise.

* sysdeps/unix/sysv/linux/kernel-features.h
(__ASSUME_RECVFROM_SYSCALL): Define by default.
(__ASSUME_RECVFROM_SYSCALL): Undef it if kernel does not support
__NR_recvfrom.

(__ASSUME_RECVFROM_SYSCALL): Remove definition.
* sysdeps/unix/sysv/linux/powerpc/kernel-features.h
(__ASSUME_RECVFROM_SYSCALL): Likewise.

(__ASSUME_RECVFROM_SYSCALL): Likewise.
* sysdeps/unix/sysv/linux/recvfrom.c: Simplify includes.
