library: fix proc_t page fault delta counts alignment

When the maj_delta and min_delta fields were added to
the proc_t, they necessitated some compiler generated
padding bytes.

With this slight reordering, those padding bytes are
no longer generated.  And since the original commit
already broke the library ABI, now is an opportune
time to correct that misalignment.
