nsscash: force UTC timezone for If-Modified-Since header

This is not strictly required as lastModified is already stored in UTC
(servers use UTC for the Last-Modified header). However, it's good
practice and prevents copy & past errors in the future. See d71bfc6
("nsscash: main_test: fix Last-Modified/If-Modified-Since headers",
2019-08-02) for the details.
