libusb: Use systemd/system

[Croydon]

Specify library name and version: libusb/1.0.23

• I've read the guidelines for contributing.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the
  conan-center hook activated.

• Depends on Add systemd/system #2468
• Blocks Remove system_requirements exception for libusb  hooks#158

@Croydon
I think this can be closed as we have a libusb/1.0.23 recipe

[Croydon]

@madebr This pr is about getting rid of the direct system requirements the libusb recipe still has

We need libudev in some Conan system package as it is part of systemd, but we don't have one yet

[madebr]

Apologies. My brain shortcuted after reading usb.

Failure in build 7 (b1019ed627ad32d7046e02a4784b192257b57889):

• Error processing recipe (ref 'libusb/1.0.23'): Linux x86_64, Release, gcc 4.9, libstdc++ . Options: libusb:shared-False
  You are depending on 'systemd/system' but it is not in the repository

There appears to be a libusb merged #4067

Can this be closed?

[Croydon]

No, this is not about adding libusb, this is about changing from a direct system dependencies on a system package, which did not make it yet over the finish line.

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
