Update "phpmyadmin" package to version 2.11.10.
Changes since version 2.11.9.6:
- [core] safer handling of temporary files with open_basedir
  (thanks to Thijs Kinkhorst)
- [core] do not automatically set and create TempDir, it might lead to
  security issue (thanks to Thijs Kinkhorst)
- [setup] avoid usage of (un)serialize, what might be unsafe in some cases

This fixes the security vulnerabilities reported in PMASA-2010-1,
PMASA-2010-2 and PMASA-2010-3.
