[pushed 3/3] [gdb] Fix dont -> don't typo

[Tom de Vries <tdevries@suse.de>]

Result of:
...
$ find gdb* -type f | xargs sed -i "s/ dont / don't /"
...
and manually fixing two hits of ' dont.'

The "dont->don't" rule is part of the code dictionary:
...
- 'code' for words from code and/or mathematics that are likely to be typos
  in other contexts (such as uint)
...
but it tries to rewrite stdio into studio, so we'll leave that disabled.

We do have a fair amount of dont_<something> in our sources, so I'm not adding
this as a rule in gdb/contrib/codespell-dictionary.txt.  It doesn't hurt us
now, but it does if we start playing with the word regexp [1].
