unix: fix build for linux/386 and linux/arm

Browse Source 
Because ARM ABI requires 64-bit argument to be passed in even
register pairs, to avoid wasting one register between fd and
advise in the usual fadvise64 syscall signature, linux/arm
has its own variation that reorders the argument so that the
arguments fit in six registers.

While we're at it, also fix build for linux/386.

Fixes golang/go#10294.
