hw_x86_64: remove aligment attribute from FPU context

Browse Source 
We do not ensure that the Fpu::Context is 16-byte aligned and,
therefore, should not tell the compiler that we did. Otherwise, the GCC
may optimize operations regarding the addresses of members as it did for

  if ((addr_t)_fxsave_area & 0xf) ...

With the declared 16-byte alignment the condition will never become
true.
