Remove cleanups from execute_gdb_command
This replaces a cleanup in execute_gdb_command with an instance of
std::string.
Testing showed that this originally missed a cleanup that was returned
by prevent_dont_repeat. This version of the patch changes
prevent_dont_repeat to return a scoped_restore rather than a cleanup.
