Drop max_sys_priv wincap

Browse Source 
Convert sys_privs to const struct with TOKEN_PRIVILEGES layout.
Drop function get_system_priv_list.  Just use pointer to sys_privs.

Dropping max_sys_priv from wincaps requires to make sure that the
bitfield is 8 byte aligned on x86_64, otherwise gcc (5.3 only?)
apparently breaks access to the bitfield (off by 4 bytes).
