plug-ins: fix resource leaks detected by coverity

Browse Source 
Several resource leaks here were detected by coverity:
- Not freeing value_utf.
- Strings returned by g_strconcat should be g_free'd. To handle the string
concatenations easier we use GString and g_string_append instead.
Also introduce function get_list_elements to reduce the number of
repetetive elements.
While we were at it, also remove unused includes.

(cherry picked from commit e90f041ca5)
