Properly lock proctree_lock before locking the process while accounting.
During the import of the MPSAFE TTY layer (r181905), I changed
acct_process() to lock proctree_lock instead of SESS_LOCK, because
s_ttyp is now locked using proctree_lock. One of the things I forgot,
was to lock it before we PROC_LOCK.
Commit this patch, written by kib@. To ensure we hold proctree_lock as
short as possible, obtaining `ac_tty' has now been made the first step
of filling `acct'.
