qmake: Use a simple response file for ar on mingw

Browse Source 
This change allows using custom flags for ar. For instance, it is
now possible to create a thin archive by setting QMAKE_LIB += -T.

This uses and extends commit d92c25b1b4ac0423a824715a08b2db2def4b6e25
which served a similar purpose for the linker.
