MinGW: Fix assert in QCoreApplication::arguments() when passing globs

We can't assume that the number of arguments we get from GetCommandLine
will match what we have from argc, as the former is not wildcard
expanded on MingGW.

mingw64 will ask __getmainargs to expand wildcards depending on
the mingw-specific variable _dowildcard. By default this is set
to 0 (false), but some mingw64-packagers (msys2, mingw-builds)
pass --enable-wildcard during build, changing this default. As
a result, the arguments we get through argc/__argc have already
been expanded. MinGW does not reflect this through GetCommandLine
though, like MSVC does, which triggered the assert.

Amends dff18b8e80609da91bf9e9134967dcf0d23eca9e.
