'distribution' facts were being set after checking
the existence of the dist file, and then being set
again with more detail after they were succesfully parsed.
But if the dist file was not succesfully parsed and
matched the required names, the loop continues
without resetting the earlier set facts. This is
how 'Mandriva' would end up being the 'distribution'
file for unrelated cases (it would find /etc/lsb-release,
set distro to 'Mandriva', then fail to parse/match and
continue the loop. If no other checks worked, 'Mandriva'
would stick).
* parse_dist_file_NA should check 'name' not distro for NA
parse_distribution_file_NA was checking the incoming
'distribution' fact to be 'NA', but the fact itself can
be specific at that point ('KDE Neon', for ex) but the
check is really if the 'name' it was passed is NA.
* for matches on OS_RELEASE_ALIAS (ie, 'Archlinux') do
not continue if the dist file content doesn't match. Previously
it had to because of the 'Mandriva' bug mentioned above.
