util: use ~ as a suffix for a temp file in the same directory as a source file
Tools like Buck have patterns to ignore the creation of files (in the working
copy) that match certain patterns:
https://github.com/facebook/buck/blob/39278a4f0701c5239eae148968dc1ed4cc8661f7/src/com/facebook/buck/cli/Main.java#L259-L299
When Buck sees a new source file (as reported by Watchman), it has to invalidate
a number of caches associated with the directory that contains the file.
Using a standard suffix, such as `~`, would make it easier for Buck and others
to filter out these types of file creation events.
The other uses of `tempfile.mkstemp()` in Hg do not appear to be problematic
because they (generally speaking) do not specify the `dir` parameter, so the
new file is created in the system-appropriate temp directory, which is outside
the working copy.
Test Plan:
`make tests`

n - skip this change
e - edit this change manually

d - done, skip remaining changes and files
a - record all changes to all remaining files
