libusb should not decide about libudev

[uilianries]

The libusb is managing what libudev can and can not do. However, libudev has a package now, where all those limitations should be managed. It was a leftover when moving the SystemPackageTool from libusb to libudev package.

Specify library name and version: libusb/1.0.24

the android check has to stay, because it won't be caught by this https://github.com/conan-io/conan-center-index/pull/9780/files#diff-c4fac46e939f790d8e094b15fd7a91507696349a250f8cd75860ae43af3b921aR64-R67

	def build_requirements(self):

	if self.options.get_safe("enable_udev"):
	if self.settings.os == "Android":
	raise ConanInvalidConfiguration("udev can't be enabled for Android yet, since libudev recipe is missing in CCI.")
	def build_requirements(self):

on Android, "libudev/system" is not part of the requirements of libusb
