Use kinfo_getfile() to implement fdwalk().

Previously, the kern.file sysctl (which queries the global file table)
was queried and the results saved in an on-stack buffer.  With a
sufficiently active system the sysctl's output could overflow the
stack's available space.  Instead, switch to kinfo_getfile() from
libutil.  This uses a sysctl which queries only the open files for the
current process, and it uses heap space instead of the stack to store
the sysctl output.
