Make thunk lib type be defined by cmake

Make the hsakmt library take the value from CMake regarding
static/shared
KFDTest automatically grabs the right one due to it checking the normal
shared folders. Tested locally (and via automation by the time that this
is merged)
Also set the default to building SOs if BUILD_SHARED_LIBS is not defined
