Fix compilation of WinCE (for both ARM and i386!) after RTL changes

* rtl/wince/Makefile.fpc: comment socket related units (which were moved)
* rtl/wince/Makefile: regenerate
* packages/rtl-extra/fpmake.pp:
    We need the sockets unit inside the win directory for WinCE as well. Best solution might be to merge the WinSock and WinSock2 units of Win32/64 and WinCE to get rid of the wince directory of rtl-extra
* packages/winceunits/fpmake.pp:
    Add rtl-extra as dependency as we need the socket related units for Bluetooth
