[dts] [PATCH V2] tests/short_live: display time in posix format and synchronize the core

[Jiale Song <songx.jiale@intel.com>]

fix 2 issue:
  1.make the core in the eal parameter consistent with the core configured by 
the config parameter.
  2.the output format of '/usr/bin/time' of FreeBSD is different from that of 
conventional Linux. add the '-p' parameter to make it output in posix format.
