QEMU_BIN_PATH is frequently set to pick up qemu binaries from "obvious"
places such as /usr/bin or /usr/local/bin. Neither of these values will
be correct for all users and both directories would typically be found
in the user's PATH. Much better to make QEMU_BIN_PATH optional and picking
up qemu via PATH instead.
Tested with ZEPHYR_GCC_VARIANT={zephyr|xtools}.
