Don't even check loca for glyph outline detection

Basically we trust the font cmap table now...

New numbers:

behdad:src 0$ time fc-scan ~/fonts/ > after-noloca

real	0m55.788s
user	0m15.836s
sys	0m17.008s
behdad:src 0$
behdad:src 0$ time fc-scan ~/fonts/ > after-noloca

real	0m24.794s
user	0m12.164s
sys	0m12.420s

Before this change it was:

behdad:src 130$ time fc-scan ~/fonts/ > after

real    0m24.825s
user    0m12.408s
sys     0m11.356s

Not any faster!  I suppose most time is being spent in loading cmap and advances now.
I'll see about loading hmtx ourselves.

With I/O numbers.  Before:

behdad:src 0$ \time fc-scan ~/fonts/ > after
11.66user 12.17system 0:24.03elapsed 99%CPU (0avgtext+0avgdata 487684maxresident)k
2320inputs+50480outputs (21major+11468549minor)pagefaults 0swaps

after:

behdad:src 130$ \time fc-scan ~/fonts/ > after-noloca
11.94user 11.99system 0:24.11elapsed 99%CPU (0avgtext+0avgdata 487704maxresident)k
16inputs+50688outputs (0major+11464386minor)pagefaults 0swaps

We are definitely doing a lot less I/O.  Surprisingly less in fact.  I don't get it.
