    [gdb/testsuite] Fix gdb.go/methods.exp with check-readmore
    
    When running test-case gdb.go/methods.exp with make check we have:
    ...
    (gdb) break main.T.Foo^M
    Function "main.T.Foo" not defined.^M
    Make breakpoint pending on future shared library load? (y or [n]) n^M
    (gdb) XFAIL: gdb.go/methods.exp: gdb_breakpoint: set breakpoint at main.T.Foo
    ...
    but with make check-readmore the XFAIL fails to trigger:
    ...
    (gdb) break main.T.Foo^M
    Function "main.T.Foo" not defined.^M
    Make breakpoint pending on future shared library load? (y or [n]) n^M
    (gdb) FAIL: gdb.go/methods.exp: gdb_breakpoint: set breakpoint at main.T.Foo
    ...
    
    This happens because this gdb_test_multiple "maintenance print symbols"
    regexp:
    ...
        -re "\r\n$gdb_prompt $" {
    ...
    matches the entire command output.
    
    Fix this by adding the missing ^ at the regexp start.
    
    Tested on x86_64-linux.
