[CRIU] [PATCH 2/6] compel: arch, x86 -- Dont require xsave_struct to be aligned

[Cyrill Gorcunov]

We don't iteract with fpu hardware directly so no need
for alignment. Moreover it will help to handle ia32 mode
where this structure won't be aligned and this is required
by a kernel to process the sigreturn frame.
