tpm2: Add quote parameter to RuntimeCommandsPrint for optional quoting

Not all callers of RuntimeCommandsPrint will want to have the returned
string use quotation marks at the beginning and end of the string.
Therefore, add a quote parameter to this function that allows to avoid
the quoting. Adapt the single caller to pass a quotation mark.
