Update CRT environment in wxSetEnv() for MinGW too.

Browse Source 
MinGW uses the same CRT as MSVC so we can use the same _putenv() call for it
too. This ensures that wxGetenv() returns the value updated by wxSetEnv() and
fixes CrtTestCase::SetGetEnv() unit test when using MinGW.

compilers/CRT implementations (currently only MSVC) and so using wxGetenv()
(notice the difference in case) may not return the updated value.
