This test provides its own mocks, so do not use the "standard"
stubs in libqemustub.a or the event loop implementation in
libqemuutil.a.

This is required on OS X, which otherwise brings in qemu-timer.o,
async.o and main-loop.o from libqemuutil.a.

1) ptimer-test is not a qtest---it runs the ptimer.c code directly in the
ptimer-test process

2) ptimer-test has its own stubs file, so there is no need to add more
stubs to stubs/vmstate.c

Ptimer is a generic countdown timer helper that is used by many timer
device models as well as by the QEMU core. Add QTests for the ptimer.
