...G...... [ZBXNEXT-1078] removed 'proc.mem[]' 5-th parameter (memtype) value 'dvm' on AIX

Before change:
    On AIX 'proc.mem[,,,,dvm]' returned the same value as 'proc.mem[,,,,size].
    No need to have 2 item keys with same value.

After change:
    5th parameter value 'dvm' removed. Use parameter value 'size' for getting size of process (code + data).
