Rename PGPROC->vacuumFlags to statusFlags

Browse Source 
With more flags associated to a PGPROC entry that are not related to
vacuum (currently existing or planned), the name "statusFlags" describes
its purpose better.

(The same is done to the mirroring PROC_HDR->vacuumFlags.)

No functional changes in this commit.

This was suggested first by Hari Babu Kommi in [1] and then by Michael
Paquier at [2].
