util/find_usbdebug: Check for lsusb and lspci

Add a check to make sure lsusb and lspci are installed, as the script
relies on them to function properly. Previously, if lsusb was not
installed, the script proceeded as if nothing was wrong, but never found
any devices plugged into the debug port. If lspci was not found, the
script exited saying that no EHCI debug capable controller was found.
The "command not found" messages that normally would have been shown in
these situations was not being shown, as stderr is redirected to
/dev/null to hide error messages that don't matter as per the comment
near the top of the script.
