Making sure kwallet is built correctly

[Marco Martin]

Hi all,
Since some binaries have been renamed in kwallet, in order for
kwallet-pam to keep working correctly, it now needs to launch ksecretd
instead of kwalletd.

If kwallet-pam is built after kwallet and is built depending from it,
everything should be already fine, otherwise if kwallet-pam was built
by manually passing -DKWALLETD_BIN_PATH  it needs to be updated as
follows:
-DKWALLETD_BIN_PATH=/usr/bin/ksecretd  (if kwwallet installs in /usr/bin)
