MinGW: fix warning in QMatrix4x4::map functions

The definitions get the following warning (treated as error):

redeclared without dllimport attribute after being referenced with dll
linkage [-Werror]

I take it to mean that because they are labelled 'inline' the compiler
disregards the 'dllimport', but that makes it inconsistent with the
declaration. So we label the declaration inline as well.
