make GetEnvironmentStringsW match windows behaviour

0009:Call kernel32.GetEnvironmentStringsW() ret=0077952f
0009:Ret  kernel32.GetEnvironmentStringsW() retval=00220000 ret=0077952f
...
0009:Call kernel32.FreeEnvironmentStringsA(00220000) ret=007795e6

looks like the programmer got things mixed up a bit :p. As wine handles the A/W
variants of that function different things explode ;). But obviously it works
on windows so this patch makes it work on wine too.
