[PATCH] m32r: fix syscall table

This patch fixes the system call table for m32r.

The latest kernel cannot be linked for m32r, because the following
experimental syscalls doesn't exist in the prepatch kernel of bk-tree.

	* include/asm-m32r/unistd.h:
	- Remove syscalls from #285(perfctr_info) to #293(keyctl).

	* arch/m32r/kernel/entry.S: ditto.
