Consolidate Linux fcntl implementation
This patch consolidates the fcntl Linux syscall generation on
sysdeps/unix/sysv/linux/fcntl.c. It basically removes all the
architecture specific implementations.
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/arm/fcntl.c: Remove file.
* sysdeps/unix/sysv/linux/generic/wordsize-32/fcntl.c: Likewise.
* sysdeps/unix/sysv/linux/hppa/fcntl.c: Likewise.
* sysdeps/unix/sysv/linux/i386/fcntl.c: Likewise.
* sysdeps/unix/sysv/linux/m68k/fcntl.c: Likewise.
* sysdeps/unix/sysv/linux/microblaze/fcntl.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips32/fcntl.c: Likewise.

* sysdeps/unix/sysv/linux/sh/fcntl.c: Likewise.
* sysdeps/unix/sysv/linux/sparc/sparc32/fcntl.c: Likewise.
* sysdeps/unix/sysv/linux/fcntl.c: New file.
* sysdeps/unix/sysv/linux/powerpc/powerpc64/fcntl.c: Refactor to
use default implementation.
