kde-plasma/kwallet-pam: Set KDE_INSTALL_LIBDIR i./o. CMAKE_INSTALL_LIBDIR

Prior to gentoo commit 7bc9e3869c, KDEInstallDirs
got its value from CMAKE_INSTALL_LIBDIR if set, which was deprecated behavior.
ecm.eclass was fixed to tick KDE_INSTALL_* variables instead of relying on
cmake.eclass to set up GNUInstallDirs, but kwallet-pam was forgotten.
