    base-files: implement ucidef_set_hostname(), ucidef_set_ntpserver()
    
    Commit 2036ae4 (base-files: support hostname and ntp servers through board.d)
    was supposed to implement these procedures but lacked the required changes
    to uci-defaults.sh.
    
    Add the missing procedures now to fix config generation on targets relying
    on hostname or NTP server presetting.
    
    Fixes FS#754.
