contrib: systemd: update deprecated StartLimit options

Browse Source 
These were originally added in 7b9ecb9700.

The `StartLimitBurst` and `StartLimitInterval` options used to be
options for `[Service]`, but were moved to the `[Unit]` in systemd 229,
and systemd 230 respectively. The `StartLimitInterval` was renamed to
`StartLimitIntervalSec`, which either takes a number (using "seconds" as
default unit) or an optional unit;

- f0367da7d1

We kept these deprecated options to provide compatibility with older distros
that not yet had systemd 230, but all distros we support are now on versions
of systemd that support the new options;

    docker run --rm registry.access.redhat.com/ubi8/ubi systemctl --version
    systemd 239 (239-82.el8_10.5)
