libusbgx: add PACKAGECONFIG to make build predicable
libusbgx: add PACKAGECONFIG to make build predicable

Also introduce a ${PN}-examples subpackage since all binaries get
built only when --enable-examples is set to true, move them into
${PN}-examples package. Another advantage of this change is that now
libusbgx only contains a .so library so the recipes DEPENDs on it wont
involve in unnecessary binaries or systemd/sysvinit scripts.

Also uprev to the latest git hash in master and fix some inconsistent
coding style and an invalid EXTRA_OECONF.
