[Tarantool-patches] [PATCH 0/3] lua/pwd: workaround the systemd bug

[Cyrill Gorcunov <gorcunov@gmail.com>]

Guys, take a look please once time permit. The first two patches
are optional but I think while we're at this code and we could
improve the code base we should.

Also I've been thinking on how to test the issue -- we need a buggy
systemd instance running and we actually have Fedora 29 on gitlab
where tests are passed but it is unclear for me how exactly we could
use it. Initially I thought of injecting some error code into pwd module
itself but then I left this idea of making code more ugly just because
of some bug in the particular systemd version.

So my criteria was that the change must not break anything in existing
tests but if you have some idea for testing, please share.
