qxl_dev: Fix alignment for QXLReleaseInfo

Do not declare the structure as aligned.
The start/end-packed.h headers affects structures without
specification only using MingW or Microsoft compilers. For other
platform SPICE_ATTR_PACKED macro should be used.  This way the
definition are the same for all compiler.
This structure is used in a lot of QXL structures which are not
aligned causing to have an aligned structure to be potentially
unaligned. Some compilers may report a warning.
As this structure has no holes this change does not make any size
change using any compiler.
The change will only change the alignment from 4/8 to 1.
This could affect structures containing this union however beside
packed structure in qxl_dev.h (which are not affected) there are no
other usages affecting ABI by spice-gtk, Qemu or spice-server.
