build-system/gnu: Gracefully handle dangling symlinks in the 'strip' phase.

Browse source 
* guix/build/gnu-build-system.scm (strip): Check whether 'file-exists?'
  before calling 'elf-file?' and 'ar-file?'.  This should fix build
  failures in the presence of dangling symlinks, as in
  <http://hydra.gnu.org/build/167521/nixlog/1/raw>.
