[OE-core] [PATCH v3] mtools-native: disable reading host configs

[Ed Bartosh]

Removed code that reads /etc/mtools.conf, /etc/default/mtools.conf,
/etc/mtools and /etc/default/mtools to ensure that mtools output
doesn't depend on the global host configs.

It's still possible to use ~/.mtoolsrc config or point MTOOLSRC
environment variable to any configuration file if user want
to configure mtools.
