source/usb: scan host sysfs

Browse source 
Scan the mounted host sysfs instead of hard coded /sys mount point.
Currently, sysfs devices subdir is not namespaced in Linux (containers
have the same view as the host) so this wasn't an issue in practice.
However, this change should make the code more future proof and align
usb with other sysfs detection in nfd.
