This is supposed to be the equivalent of __NR_syscalls, not
__NR_syscalls -1. The x86 code this was based on had simply fallen
out of sync at the time this was implemented. Fix it up now.
As a result, tracing of __NR_perf_counter_open works as advertised.

It seems that MCOUNT_INSN_OFFSET was calculating the distance between
the wrong functions. The value that should have actually been computed
is the distance between ftrace_call and ftrace_stub. I discovered this
when I added some code to ftrace_caller.
