libcacard: replace qemu thread primitives with glib ones

Replace QemuMutex with GMutex and QemuCond with GCond
(with corresponding function changes), to make libcacard
independent of qemu internal functions.

After this step, none of libcacard internals use any
qemu-provided symbols.  Maybe it's a good idea to
stop including qemu-common.h internally too.
