[gdm] gdm-common: Drop some dead code

    gdm-common: Drop some dead code
    
    -unknown-origin.[ch] according to ChangeLog was about copyright
    status...but the file clearly has a copyright header now, so
    presumably this is just long dead history.
    
    Nothing was using gdm_safe_fopen_w().  After deleting that, we're left
    with VE_IGNORE_EINTR(), which is now just in gdm-common.h
