kcheckpass: fix shadow support when not building tdm
1. If not building with PAM, kcheckpass relies on HAVE_SHADOW to decide whether to support shadow passwords. However, this was only set if also building tdm. Consolidate all PAM/shadow configure checks at the top level so these are always set correctly. 2. Consolidate /etc/passwd and shadow password handling The shadow password handler already completely handles /etc/passwd passwords as well, so having a separate handler for just /etc/passwd is pure code duplication. Signed-off-by: Bobby Bingham <koorogi@koorogi.info>
