patches/openwrt: add patch to fix detection of enabled service

The services such as umount do not have START but they have STOP. The original implementation of enabled considered only START but both of them should be considered.

Upstream MR: https://github.com/openwrt/openwrt/pull/4235

+Subject: [PATCH] base-files: fix enabled for services with only STOP
+MIME-Version: 1.0

+
+There are services that have only STOP value set. They are executed only
+on shutdown and it is common to use them for system cleanup. There is
+one such service shipped directly with base-files, it is 'umount'. Those
+work the same way as those with START but enabled does not report them
+as enabled although it should have as they can be enabled and disabled
+as any other service.
