Bug#932201: wine64 should also look for /usr/lib/wine/wineserver64 if WINESERVER is not set

[Daniel Kahn Gillmor <dkg@fifthhorseman.net>]

Package: wine64
Version: 4.0-2
Severity: normal

wine64(1) says:

    WINESERVER
              Specifies  the  path  and  name of the wineserver binary. If not
              set, Wine will try to load /usr/lib/wine/wineserver, and if this
              doesn't exist it will then look for a file named "wineserver" in
              the path and in a few other likely locations.

But wine64 only ships with /usr/lib/wine/wineserver64.

I'm finding that i need to set WINESERVER=/usr/lib/wine/wineserver64
in libgpg-error's debian/tests/windows (an autopkgtest where we ensure
that we can build a static windows executable against libgpg-error on
debian), otherwise i get "could not exec wineserver".

It seems like wine64 should be smart enough to try
/usr/lib/wine/wineserver64.

 (aside about the overall problem space of using wine in autopkgtest:
  i think if i installed the "wine" package, and then just invoked
  /usr/bin/wine directly, instead of wine64, it would work correctly
  for me, but the problem with that is that "wine" sends a warning to
  stderr about wanting wine32 installed upon every invocation, which
  isn't possible on a non-multiarch system (and all the continuous
  integration systems i've used thus far are non-multiarch).  And
  messages to stderr are indicators to autopkgtest that the test is a
  failure.  I could suppress the warning by setting WINEDEBUG=-all,
  but i *don't* want to suppress any other warnings that wine might
  produce.  So if you see a better way around this, so that i can use
  wine in autopkgtest more easily, please don't hesitate to suggest
  it)

        --dkg
