build info: change ID and Release

build info: change ID and Release

- ID format is changed to get the value from Version.Build
  = Previous Build ID example
    : tizen-mobile_20160308.8_mobile-wayland-armv7l-tm1
  = Changed Build ID example
    : tizen-mobile

- Release value is changed to get the value from Version.Build
  = Previously, the value was created by removing alphabet
    from Version.Build. However the Version.Build could contain
    other numbers between alphabets. Thus Release value
    could be weird.
  = Now, Release value is parsed from Version.Build by
    the Build.Date value.
