node-util: RHBZ#1005307 refactor oo-restorecon to accept files as arguments

Reworking the oo-restorecon script to accept files as arguments. I kept the chcon all gears option just in case.

```
# oo-restorecon
Usage: /usr/sbin/oo-restorecon [options] [UUIDs]
    -v, --verbose                    Verbose output
    -a, --all                        Chcon all gears
    -h, --help                       Display help
#
```
```
# oo-restorecon -a
# 
```

```
# oo-restorecon -a -v
