fix(coresmd): trim quotes on cert path to actually ignore if empty

Passing '' or "" as an empty argument would see the cert path be
literally quotes (e.g. "" or ''). This commit ensures those characters
are trimmed from the output (shallowly) so the string appears as empty
when checking if the cert path is set.
