Motivation for this change

I noticed several getfacl messages about absolute paths in our tests logs.

Default getfacl behavior is to remove leading slash on absolute
paths in its header printed to stdout.
Before the header it will also print a message about it...

Switches -p -or --absolute-names can turn this off
and remove some noise from our tests logs.

output with noise:

$ getfacl /dev/snd/timer
getfacl: Removing leading '/' from absolute path names
# file: dev/snd/timer
# owner: root
# group: audio
user::rw-
user:demo:rw-
group::rw-
mask::rw-
other::---

-vs- a clean output:

$ getfacl -p /dev/snd/timer
# file: /dev/snd/timer
# owner: root
# group: audio
user::rw-
user:demo:rw-
group::rw-
mask::rw-
other::---
