perf/core, sched: Don't use clock function pointer to determine clock

Now that local_clock() is explicitly inlined in sched.h, taking its
pointer would uninline it in the compilation unit where it's done,
making (among other things) comparing pointers to this function
produce different results in different compilation units.

Case in point, x86 perf core's user page updating function compares
event's clock against &local_clock to see if it needs to set zero
time offset related bits in the page.

This patch fixes the latter by looking at the "use_clockid" event
attribute instead, to determine whether local clock is used. Fixing
the uninlined local_clock() in perf core is left as an exercise for
the author of the prior work.
