Use the sf_buf facility rather then kmem_alloc_wait/pmap_kenter/kmem_free
to map the first page of a binary into memory during an exec.  This results
in 5-10% lower execl() overhead and approximately 2% lower sys time useage
in a buildworld (~15-20 second build time reduction on an AMD64/3200+),
with less code.  And its a nice cleanup as well.
