Lennart Poettering 97f0e76f18 user-util: rework maybe_setgroups() a bit 
Let's drop the caching of the setgroups /proc field for now. While there's a
strict regime in place when it changes states, let's better not cache it since
we cannot really be sure we follow that regime correctly.

More importantly however, this is not in performance sensitive code, and
there's no indication the cache is really beneficial, hence let's drop the
caching and make things a bit simpler.

Also, while we are at it, rework the error handling a bit, and always return
negative errno-style error codes, following our usual coding style. This has
the benefit that we can sensible hanld read_one_line_file() errors, without
having to updat errno explicitly.
