frigate: do not mount /etc/localtime

Fedora CoreOS has no /etc/localtime, and podman fails the start of the
container on a missing mount source (exit 125, "statfs /etc/localtime:
no such file or directory"). Frigate files its recordings by UTC date,
and its web interface shows the time zone of the browser.
