x86: properly define size_t
Having it defined unilaterally as 'unsigned long' got me surprised
recently when I tried to use the 'z' printk type modifier, as that is
expected by the compiler to be used only on the type it knows size_t
is supposed to have.
Generally the compiler provides a construct to do this, so use it when
available.
