[issue38417] Add support for settting umask in subprocess children

[Gregory P. Smith]

Gregory P. Smith <greg at krypto.org> added the comment:

We don't have to for all possible things, doing this just reduced friction for existing uses.  In this case, calling umask in our child ourselves would be easy to support.  (easier than the more important setuid/sid/gid/groups-ish stuff that recently went in)

I'm trying to make sure we track what is blocking people from getting rid of preexec_fn in their existing code so that we can actually deprecate and get rid of the API entirely.
