  MFC r274846:
  
  Fix the following -Werror warning from clang 3.5.0, while building
  usr.bin/cpio on amd64 (or any arch with 64-bit time_t):
  
  contrib/libarchive/cpio/cpio.c:1143:6: error: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value [-Werror,-Wabsolute-value]
  	if (abs(mtime - now) > (365/2)*86400)
  	    ^
  contrib/libarchive/cpio/cpio.c:1143:6: note: use function 'labs' instead
  	if (abs(mtime - now) > (365/2)*86400)
  	    ^~~
  	    labs
  1 error generated.
  
  This is because time_t is a long on amd64. To avoid the warning, just
  copy the equivalent test from a few lines before, which is used in the
  Windows case, and which is type safe.
