mingw.c: move definition of mingw_getenv down

Browse source 
We want to use static lookup_env() in a subsequent change.

At first sight, this change looks innocent. But it is not due to the
#undef getenv. There is one caller of getenv between the old location and
the new location whose behavior could change. But as can be seen from the
defintion of mingw_getenv, the behavior for this caller does not change
substantially.

To ensure consistent behavior in the future, change all getenv callers
in mingw.c to use mingw_getenv.

With this patch, this is not a big deal, yet, but with the subsequent
change, where we teach getenv to do a case-sensitive lookup, the behavior
of all call sites is changed.
