gdb: fix some clang-tidy readability-misleading-indentation warnings

I have warnings like these showing in my editor all the time, so I
thought I'd run clang-tidy with this diagnostic on all the files (that I
can compile) and fix them.

There is still one warning, in utils.c, but that's because some code
is mixed up with preprocessor macros (#ifdef TUI), so I think there no
good solution there.
