Silence STDERR in Facter

[dennisdegreef]

Currenly performing a puppet apply, the following output is shown

Info: Loading facts
160903 16:55:09 [Note] /usr/sbin/mysqld (mysqld 10.0.26-MariaDB-0+deb8u1) starting as process 6358 ...
Notice: Compiled catalog for foo.example.com in environment production in 1.52 seconds

This is due to Facter performing mysqld -V to determine the version as fact.

The output of this command alone is this:

$ sudo mysqld -V
mysqld  Ver 10.0.26-MariaDB-0+deb8u1 for debian-linux-gnu on x86_64 ((Debian))
160903 17:02:08 [Note] mysqld (mysqld 10.0.26-MariaDB-0+deb8u1) starting as process 7260 ...

Where the line with 'starting as process' is STDERR.

This diff redirects STDERR to /dev/null, since it probably contain any critical information (during a version check).

After applying this diff, the expected outcome is the same again

$ sudo mysqld -V 2>/dev/null
mysqld  Ver 10.0.26-MariaDB-0+deb8u1 for debian-linux-gnu on x86_64 ((Debian))

As well as within Puppet.
