Reuse kern_proc_vmmap_resident() for procfs_map resident count.

The existing algorithm in procfs_map() to calculate count of resident
pages in an entry is too primitive, resulting in too long run time for
large sparse mapping entries.  Re-use the kern_proc_vmmap_resident()
from kern_proc.c which only looks at the existing pages in the
iterations.

Also, this makes procfs to honor kern.proc_vmmap_skip_resident_count,
if user does not need this information.
