gallium/util: fix crash with daz detection on x86
The code used PIPE_ALIGN_VAR for the variable used by fxsave, however this
does not work if the stack isn't aligned. Hence use PIPE_ALIGN_STACK function
decoration to fix the segfault which can happen if stack alignment is only
4 bytes.
This fixes https://bugs.freedesktop.org/show_bug.cgi?id=87658.
