Remove unused macros from i386 lowlevellock.h.

In the course of the work on six-argument syscalls I noticed that the
i386 lowlevellock.h contained some unused macro definitions (already
unused before my patch).  This patch removes them.

Tested for x86 that installed stripped shared libraries are unchanged
by this patch.

	* sysdeps/unix/sysv/linux/i386/lowlevellock.h (LLL_EBX_LOAD):
	Remove macro.
	(LLL_EBX_REG): Likewise.
	(LLL_ENTER_KERNEL): Likewise.
