runtime: align m.procid to 8 bytes on 32-bit systems
https://go-review.googlesource.com/c/go/+/383434 started using
atomic Load64 on this field, which breaks 32 bit platforms which
require 64-bit alignment of uint64s that are passed to atomic operations.
Not sure why this doesn't break everywhere, but I saw it break on
my laptop during all.bash.
