    time applet: fix a build problem with kernel versions missing O_CLOEXEC symbol
    
    Kernel versions < 2.6.23 do not support/provide O_CLOEXEC symbol
    causing the time applet not to compile:
    
     miscutils/time.c: In function 'time_main':
     miscutils/time.c:445:28: error: 'O_CLOEXEC' undeclared (first use in this function)
     miscutils/time.c:445:28: note: each undeclared identifier is reported
      only once for each function it appears in
    
    Fix it by using close_on_exec_on function provided by libbb
    instead of passing O_CLOEXEC flag to open.

     v2: remove unnecessary "if (output_fd >= 0)", xopen guarantees the returned
         file descriptor to be valid, thanks to Xabier Oneca for pointing it out
