rpm: avoid empty plugindir error

When using dnf/rpm, we'll see error messages like below:

  error: /usr/lib64/rpm/macros: line 1183: Macro %__plugindir has empty body

The problem was introduced by the following commit in RPM upstream:
https://github.com/rpm-software-management/rpm/commit/ab28534f9e68aff8be65cd1adbac86b5a2cafde4

We'll need to move RPM_PLUGINDIR definition to top-level CMakefile.txt
to solve this problem.

+Subject: [PATCH] Set RPM_PLUGINDIR in top level CMakeLists.txt
+
+We have in macros.in:
+  %__plugindir          @RPM_PLUGINDIR@
+
+This means, if RPM_PLUGINDIR is not set, %__plugindir will be empty.
+This in turn results in error message when running 'dnf'.
+
+e.g.,
+dnf --help >/dev/null
+error: /usr/lib64/rpm/macros: line 1183: Macro %__plugindir has empty body
+error: /usr/lib64/rpm/macros: line 1183: Macro %__plugindir has empty body
+
+So we should move this directory setting into the top level CMakeLists.txt.
