[clang-rename] Use checktime when reloading vim buffer after applying clang-rename

After applying `clang-rename` to a vim buffer (using `clang-rename.py` as part
of the vim integration) the buffer gets reloaded using `bufdo`. This solution is
suboptimal, since syntax highlighting is turned off for performance reasons and
never turned on, after all changes to the source file have been applied.

A better solution to this is using `checktime`. It is exactly designed for this
kind of task and doesn't have the syntax highlighting issue.
