[Spice-devel] [PATCH spice-server] build: do not warn about address-of-packed-member

[Uri Lublin]

The gcc warning address-of-packed-member is new and on by
default in gcc 9.

Many of the structures sent over the network are packed
and with unaligned fields.

This breaks the build -- due to -Werror.
Tell gcc to not warn about it.
