    [gdb/testsuite] Fix gdb.debuginfod/fetch_src_and_symbols.exp with check-read1
    
    With test-case gdb.debuginfod/fetch_src_and_symbols.exp and check-read1, I run
    into:
    ...
    (gdb) FAIL: gdb.debuginfod/fetch_src_and_symbols.exp: local_url: \
      file fetch_src_and_symbols (got interactive prompt)
    ...
    
    The problem is that this output:
    ...
    Enable debuginfod for this session? (y or [n]) y^M
    ...
    is matched using regexp "Enable debuginfod?.*" with matches only the first two
    words of the output, after which an implicit clause in gdb_test_multiple triggers
    on the second part containing the interactive prompt.
    
    Fix this by included the interactive prompt in the regexp.
    
    Tested on x86_64-linux.
