Use msgget syscall for Linux implementation

This patch add a direct call to msgget syscall if it is supported by
kernel features.

hecked on x86_64, i686, powerpc64le, aarch64, and armhf.

	* sysdeps/unix/sysv/linux/alpha/syscalls.list (msgget): Remove.
	* sysdeps/unix/sysv/linux/arm/syscalls.list (msgget): Likewise.
	* sysdeps/unix/sysv/linux/generic/syscalls.list (msgget): Likewise.
	* sysdeps/unix/sysv/linux/hppa/syscalls.list (msgget): Likewise.

	* sysdeps/unix/sysv/linux/s390/s390-64/syscalls.list (msgget):
	Likewise.
	* sysdeps/unix/sysv/linux/x86_64/syscalls.list (msgget): Likewise.
	* sysdeps/unix/sysv/linux/msgget.c (msgget): Use msgget syscall if
	define.
