top: ensure necessary proc_t support if '-U' filtering

While the effective user id would always be present in
each proc_t, thus supporting 'u' filtering, other user
ids would only be present if /proc/$$/status was read.

This commit just puts the 'master' branch top on a par
with the 'newlib' branch when user filtering with 'U'.
