Matthew Rosato 6235a51d7c libutil: add example for util_lockfile ...

Adds util_lockfile_example.c, which can be used to sample
util_lockfile support.

To acquire a lock using a parent PID (e.g. your shell instance):
util_lockfile_exmample -f <path> -l <retries>

To release the lock using the parent PID:
util_lockfile_example -f <path> -r

To acquire the lock, sleep briefly, and then release the lock
using the PID of the util_lockfile_example process:
util_lockfile_example -f <path> -L <retries>

In each example, the <path> is the location of the desired lockfile
and <retries> is the number of times to retry acquiring the lock
if it fails.
