Drop old trigger scriptlet

1.15.1 was ~2017, so there is no need to support upgrades from such old
systemd. This allows the dependency on grep to be dropped. grep pulls
in pcre, but most other programs in the core group depend on the newer
pcre2, so it's nicer to avoid pulling in pcre in minimal installations.
