Cygwin: cygserver: drop useless packed attribute 

...from structs used for data exchange between clients and cygserver.
All of the structs have the same size and member offsets, packed or
unpacked.  Keeping the packed attribute results in ominous warnings
from gcc-9.2.0:

  cygserver.cc:259:10: warning: taking address of packed member of
  'client_request_attach_tty::request_attach_tty' may result in an
  unaligned pointer value [-Waddress-of-packed-member]
