    [gdb/testsuite] Add kfail in gdb.dwarf2/dwzbuildid.exp
    
    When running test-case gdb.dwarf2/dwzbuildid.exp using target board readnow, I
    get:
    ...
    (gdb) file dwzbuildid-mismatch^M
    Reading symbols from dwzbuildid-mismatch...^M
    warning: File "dwzbuildid5.o" has a different build-id, file skipped^M
    could not find '.gnu_debugaltlink' file for dwzbuildid-mismatch^M
    (gdb) delete breakpoints^M
    (gdb) info breakpoints^M
    No breakpoints or watchpoints.^M
    (gdb) break -qualified main^M
    No symbol table is loaded.  Use the "file" command.^M
    Make breakpoint pending on future shared library load? (y or [n]) n^M
    (gdb) FAIL: gdb.dwarf2/dwzbuildid.exp: mismatch: gdb_breakpoint: set breakpoint at main
    ...
    
    This is PR symtab/26797: when using readnow, a failure in reading the dwarf
    results in the minimal symbols not being available.
    
    Add a corresponding KFAIL.
    
    Tested on x86_64-linux.
