    opkg: add strict package matching on removal patch
    
    During removal, opkg is using globs to select which metadata files to
    remove. The glob is too broad and sometimes can result in a package
    removing the metadata from a package with a close name. Make the
    matching more strict.
    
    Fixes bugzilla 12905

+Subject: [PATCH] remove_maintainer_scripts: use strict matching
+
+The function is using a glob to select which metadata files needs to be
+deleted during package removal, on the info_dir. However, the glob may
+match metadata files from packages with similar names. For example,
+during removal of package glibc-binary-localedata-de-at, the current
+logic was also removing the metadata for
+glibc-binary-localedata-de-at.iso-8859-1. Add check for an exact match
+before deletion.
+
+Fixes bugzilla: 12905
