Obsolete PT_STEP and friends, that have never been implemented.

Browse Source 
PT_STEP was exposed to userland for NetBSD 1.6 to 9, and
PT_SETSTEP and PT_CLEARSTEP was for 8 to 9. Therefore, they cannot be
reused for other purposes.

PT_STEP was introduced to arm/ptrace.h rev 1.2:

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/arm/include/ptrace.h#rev1.2

This was for workaround against GDB, which assumes PT_STEP is 9 (even
today!!), if it is undefined. But, this should have been dealt with
differently...
