Subject: [PATCH 2/4] nixos/zoneminder: also run zmupdate "freshen" on start

-f "freshen the configuration in the database", which will matter when
ZoneMinder adds a new configuration item [1]. Although it can also be
run without a new configuration item too; upstream's Debian postinst
code always run it on upgrade [2].

Subject: [PATCH 3/4] nixos/zoneminder: requires `sysvsem` PHP extension

This is used in ZoneMinder since some time ago [1]. Without this
extension, controling of playback (play, pause, fast forward, etc.) will
not work.

Subject: [PATCH 4/4] nixos/zoneminder: automatically update Nix store path in
 config DB

ZM has a configuration which defaults to a file in its installaton path.
In NixOS, this means a Nix store path is persisted into the database,
which will break when e.g. ZM is upgraded.

Workaround this by doing a regular expression-based string replacement
SQL command to replace this value. The regular expression should not
match if users has changed this config to somewhere else. It will match
even if ZM isn't upgraded, in which case it'll replace the value with
itself. As such, it should be safe to run this at every ZM startup.
