  copy-file-range: work around Linux kernel bug
  
  This workaround is adapted from Coreutils.
  * lib/copy-file-range.c [__linux__ && HAVE_COPY_FILE_RANGE]:
  Include <sys/utsname.h>.
  (copy_file_range): Use a stub to replace the copy_file_range of
  Linux kernel versions 4.5 through 5.2.
  * lib/unistd.in.h (copy_file_range):
  * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS):
  * modules/copy-file-range (configure.ac):
  * modules/unistd (unistd.h):
  Support replacement of copy_file_range.
  * m4/copy-file-range.m4 (gl_FUNC_COPY_FILE_RANGE):
  Define HAVE_COPY_FILE_RANGE if the system has copy_file_range,
  and on Linux check whether the system’s is known to work.
