Subject: [PATCH] install: when looking for a unit file for enabling, search
for templates only after traversing all search directories
Let's always make sure to look in all search directories for the full
unit names first, before looking for templates for them.
(cherry picked from commit e50bd775163cd96be1888943a8785a436be710e8)
