Enable excluded lint checks

There are a set of lint checks that are disabled by default with
golangci-lint. This enables them by setting exclude-use-default to
false.

This by itself triggers a set of lint failures due to these additional
checks. To by systematic about addressing these potential issues, this
adds those checks back as individual exclusions so they can be addressed
on by one.

This eliminates one of those individual checks by addressing cases of
"Potential file inclusion via variable" where passed in variables are
used in os.OpenFile calls.
