Fix regression in using window message names (#2925)

FreeRDP defines macros WM_LBUTTONUP, WM_LBUTTONDOWN, WM_RBUTTONUP
and WM_RBUTTONDOWN. These conflict with the definitions we have in
xrdp_constants.h. Because the FreeRDP system includes followed the local
includes however, the compiler did not emit a diagnostic for this -
see gcc bug #16358.

This PR rearranges the includes for NeutrinoRDP so the macro
redefinitions are flagged by the compiler.
