sys/vmmeter.h: Fix trivial '-Wsign-compare' warning in common header

Frankly, it doesn't make sense for vm_pageout_wakeup_thresh to have a negative
value (it is only ever set to a fraction of v_free_min, which is unsigned and
also obviously non-negative). But I'm not going to try and convert every
non-negative scalar in the VM to unsigned today, so just cast it for the
comparison.

vm/vm_page.h: Fix trivial '-Wpointer-sign' warning

pq_vcnt, as a count of real things, has no business being negative. It is only
ever initialized by a u_int counter.

The warning came from the atomic_add_int() in vm_pagequeue_cnt_add().

Rectify the warning by changing the variable to u_int. No functional change.
