Matthias Treydte 0c9a754a6c prometheus: fix build when all service discovery plugins are disabled
Since c6fae8bb0e, when all discovery
plugins are disabled, the postPatch phase contains shell code like

> ( ) > plugins.yml

which is invalid syntax. So make sure there's always at least
one statement for the subshell, giving the expected empty file.
