build-system/gnu: Tolerate errors during the 'strip' phase.

This is a followup to commit 9a87649c863e1ff8b073b356875eb05eecedbcf7.

* guix/build/gnu-build-system.scm (strip)[strip-dir]: If an invoke error
occurs, issue a warning and continue to the next file.  This restores the
tolerance of stripping errors prior to commit 9a87649.
