    initgroups.3: Clarify that ENOMEM is a possible value for 'errno'
    
    The current phrasing could be interpreted as meaning that initgroups(3)
    could return ENOMEM instead of -1, which it actually did until I fixed
    it in commit 0b018cfd81d8 ("initgroups(3): Fix return value on
    allocation failure").
    
    While here, mention setgroups(2) as a system call rather than a library
    function.
