[OE-core] [PATCH v3] systemd: Add partial support of drop-in configuration files to systemd-systemctl-native

[Frederic Ouellet]

Support for <service name>.d/ folders containing .conf files
It doesn't support all the partial folder names

See https://www.freedesktop.org/software/systemd/man/systemd.unit.html
