configure.ac: fix HAVE_SYNC_FILE_RANGE definition

If sync_file_range is not available when building the configure script,
there is a cosmetic bug when running that script reporting
"HAVE_SYNC_FILE_RANGE: command not found".  Remove that error message by
defining HAVE_SYNC_FILE_RANGE to an empty string, rather than generating
a script where that appears as a bare command.
